You have been subscribed to a public bug:

When I'm using complex executions in Gimp like GAP or script-fu or likewise, in a few uses it simply freezes and never get unfreezed. 
The same when I run gksu many times.

It is easy to reproduce in gimp. Try it:

1 - Open Gimp
2 - Open any little image (200x200) in another window (in the same gimp).
3 - Create a new little (200x200) image (separate, not a layer of the previous)
4 - Save it as file_0001.xcf (for GAP compliance)
5 - Go to Video -> Duplicate frames and choose almost 30.
6 - Go to Video and  "Move path..."
7 - In the dialog select source image as the opened first (in the step 2 of this guide).
8 - Play with it putting points (just follow GAP guide -> http://www.gimp.org/tutorials/Advanced_Animations)
9 - Click in "Preview animation" button and wait.

Do the above two, three or more times... your gimp will become freezed
and will stay so for a couple of hours (if not all the time).

So, how to work with that?

The same problem with gksu:
1 - Open a terminal
2 - Execute "gksu <something>". <something> maybe just synaptic -> gksu synaptic
3 - Put the password
4 - Close the "gksued" program (synaptic in this example).
5 - Wait some time for the password to expire.
6 - Repeat from 1

When you repeat it many times you will get a gksu freezed the same as
gimp just next you put the password. So, the only option to continue is
killing gksu. If not you will not see nothing (neither the gksued
program) but gksu is freezed.

This problem is from version 9 to 10 of Ubuntu. I'm tired about this
problem and I have years waiting for the next release of Ubuntu for a
solution but never happens.

So, people, (just kidding): What are you waiting for... Christmas?

Really I'm reporting this because it is a real problem and comes from
years ago. I'm tired searching for a solution and nobody talks about a
solution from root of this problem (ony failed workarounds). I guess the
problem can be related with dbus communication.

I don't understand how the visual applications communicates each other,
but I guess there is the problem. Because the first time when Gimp
becomes freeze I just read about a similar problem with gksu in a forum.
The guy suggested to remove some gnome applet. I just removed the "Wanda
the fish" and gimp unfreezed. But right now I removed all applets and
gimp still stay freezed (for at least 20 minuts). And I removed
metacity, gnome-panel using killall. Executed all newly but Gimp stay
freezed. And right now (when I'm writing this) Gimp is still freezed. No
matters what I do with the all other applications but I guess there will
be some awaiting communication what never will happens. Because a lost
of sync or something like that? So, please, get a real solution I need
to work with GAP and I'm tired experimenting with all the system
searching for a solution.

And when GKSU becomes freezed (running from the system itself) it
freezes all the desktop. When that happens I cannot interact with
anything (neither panel, Alt+Tab, Alt+F2, or whatever, all is freezed).
So I must press Ctrl+Alt+F1, login and execute -> killall gksu. When I
return with Alt+F7 all the desktop is unfreezed. What the f**??

So that is a serious problem and it happens in my desktop computer, in a
desktop computer of a friend, in a virtualbox machine running an ubuntu
for installing to friends, and in my ubuntu in my netbook too. All
versions from 9.04 to 10.04. So it is not an isolated problem of my own
computer or system configuration.

I guess this bug is still present in 10.10 because nobody is talking
about this. But I guess too it is little known because the people don't
use a Linux Box like me, so it becomes unnoticeable but it is present
hidden in some place. Really.

But, as I said: You can trigger it as described above. It is too easy to
trigger for me so becomes a annoyance. I cannot work so with my
computer.

I tried in KDE but the same. I don't tried it in xfce but I guess will
happen the same. But anyway I like to work in gnome not KDE or XFCE. So,
help me to solve it people, please :P (I don't know how to request you
guys :P)

Here you can see a video reproducing it ->

Bye and thank you.


My System:
Description:	Ubuntu 10.04.1 LTS
Release:	10.04


Latest news:
I forced to close Gimp and it still let opened some windows just the corresponding to some scripts of GAP. I will attach the screenshots. I tested if I just kill that windows instead of Gimp it get unfreezed (like killing gksu). The last may work as a workaround in Gimp for now (just killing the script or the script window dialog).
