There seems to be a problem with the eeschema

I've now checked the BZR versions that I've been running lately,
and it works in BZR 3001 and 3153, and is broken in 3212,
3221 and 3226 (so it broke somewhere between 3153 and 3212).
I've updated my Debian recently, so I pulled BZR 3001
again (had deleted it :-) and the latest (BZR 3226), and
compiled both, to see if the problem was (in some obscure way)
related to library files on my system that have been upgraded
since compiling the various versions of kicad (No, it isn't ...).
To recreate:
Start eeschema,
start the Library Editor,
"Select working library",
(any library that you have write access to, e.g. in your project dir)
"Load component to edit from the current lib",
(any component will do)
"Create a new component from the current one",
(or change the component in some way, or create a new
component, or ... - anything that's considered a change)
"Update current component in current library",
(this step can be skipped - the next step will
then ask for inclusion of the changes, which
doesn't make any difference on the behaviour)
"Save current library to disk"
Include last component changes? Yes
Modify library file "<name>.lib"? Yes
Now, the <name>.lib and/or <name>.dcm file(s) should have been
updated, but no, they're not, and the "Save current library to disk"
icon (far left) doesn't inactivate (gray out) either.
I do not have this problem on 64 bit Debian Testing using KiCad version BZR
3226 and wxWidgets 2.8.12 even with all of the fancy new Gnome 3 stuff. The
library file changes are saved properly and the save current library tool bar
icon and file menu entry are disabled as expected.
Well, I kinda suspected that, as such a major
problem probably couldn't go unnoticed for long :-)
I'm also using 64-bit Debian Testing, but with wxWidgets 2.8.10.1-3.1.
With wxWidgets upgraded to 2.8.12.1-2, I've now recompiled a
clean BZR 3226 tree with $MAKE unset (normally set to "make -j5").
The problem isn't in wxWidgets or the parallel
make, as the problem still persists :-(
Since you don't see this problem on a similar system, it sounds like
my system contains a buggy version of some (other) library - one that
contains a feature not used in kicad until somewhere between 3153 and 3212.
Even though I upgraded only a few weeks ago, apt-get now wants
to update almost 1k packages (out of 3k), so I think I'll do a
full (dist-)upgrade tomorrow, and see if that makes a difference.
Btw., the only warnings (no errors) I got from the 3226
compile was these, which AFAICS doesn't affect eeschema:

Let's see if we can save the changed/new part to a new library:
"Save current component to new library"
Yes :-), the file <part>.lib is created (in the current dir).
The file <part>.dcm doesn't get created, but it didn't either
in the earlier versions of kicad (maybe it should ?).
You should have gotten a warning dialog that your new library needs to be
added to the project at this point.
Yep, I did get that warning dialog.
Save to new lib was only to verify that the lib editor could still save
a file, and that it would choose the correct directory (the project dir).
The only way to exit the library editor is to discard all changes:
"Quit"
Library "<name>" was modified!
Discard changes?
No -> Can't quit library editor :-(
Yes -> The changes made are lost :-(
This is the correct behavior. You didn't save the changes you made to the
current component to the current library. You only save them to a new
library which is what you requested. The modified component in the currently
library still exists. The new library is not loaded when you saved the
modified component to a new library that's why the save current library tool
bar button is still enabled. You must open the library dialog in the
preferences menu and add your new library to the project in order to use it.
I don't ever remember the library editor ever behaving differently than this.
Well, I _did_ try to save to the selected lib first, but nothing happened :-(
The running eeschema _does_ seem to remember the changes, though,
so I didn't notice the failure to save the changes to disk at first
(thought it was just a minor problem with the "changes made" flag) ...
... at least until I deleted the *-cache.lib files, and then
suddenly parts disappeared or reverted back to an older version :-(
Fortunately, it was only a few simple changes ...
Btw., "bzr -r revno:3001 update" _does_ downgrade the source to
BZR 3001, and the resulting kicad _is_ the older version (old style
icons and layout, and w/o the lib editor bug), but it presents
itself in the kicad titlebar as the newest BZR release ?
This was a bit confusing at first ...
Run "make rebuild_cache" before running "make" to update the version file
every time you update your source branch. Otherwise the version file will be
out of synch with the repo version.
This was just a minor confusion, but as I copy (rsync) a clean and
freshly updated (or in this case, downgraded) bzr source tree to another
location for cmake + make, I found this behaviour a bit strange.
"make rebuild_cache" sounds like the right cure, although
I don't quite understand why it should be necessary.
... unless the bzr tree contains a file with the newest known release
no. in it, which then gets used by kicad (w/o the "make rebuild_cache").
