[Bug 913930] Re: strange error leads to broken project file
So, I didn't find the reason of this error. I just finished my project again from last good working backup.
Hope this error will never appear again.
Thanks for trying to help.
Now you can close this bug.

Title:
strange error leads to broken project file
Status in OpenShot Video Editor:
New
Bug description:
Hi there!
There is a great fault happened with my openshot project: several days
work gone away. I hope there is any way to fix it, cause it left five
minutes to finish work on project.
I worked with project and everything was great. I have five tracks in
my project (actually 1 and 2 are empty, 3 is for sound and 4 and 5 is
for video). Suddenly tracks 1 to 3 dissapeared (I added or removed
nothing from project at this moment, just was moving clips already in
project). There still exist in project, but I don't see them and
cann't modify them. I thought that it is just bug with GUI (openshot
is still has some bugs and restart is a good way to fix it). So I
restarted it.
Unfortunately, my project didn't open. It stops on error:
ALSA lib pcm.c:7316:(snd_pcm_recover) underrun occurred
/usr/lib/pymodules/python2.7/openshot/classes/sequences.py:779: GtkWarning: gdk_pixbuf_scale_simple: assertion `dest_width > 0' failed

OpenShot has failed to import some of the Python files or libraries
required for our application to run. Here are some trouble shooting
tips:
Tip 1) Check if MLT can be successfully imported in Python. Run the
following commands, and see if any errors are displayed. If you get
an error, you need to investigate the correct way to install MLT.
NOTE: Do not type the $ or >> characters in the examples below.
$ python
>> import mlt
>> mlt.Factory().init()
Tip 2) If MLT is working from the first example, then the next tip is
to look at the above error messages very closely, and google for more
help. It's likely the problem is already reported, and maybe there is
a simple work-around. Also, you can search for bugs or report a new
bug at https://bugs.launchpad.net/openshot. Good luck!
There was no way to open it. I have a backup, but it is too old. I tried to play with diff from my current project and backup (I made a patch from it, and removed some part of it, but there was no any success, error still appeared).
After some time I tried to open my file via `recently used` menu item.
It opened!! But still without tracks 1 to 3. Then I tried move 4th
track down. After that 3 track appeared. So, seems, that 4th track is
buggy. But I don't know, how to fix it, cause I don't know a reason of
this error.
Also all transitions between clips disappered. They are present in
movie, but I can't see and edit them.
Are there any chances to back my project back and are there any
chances to not get such error again?
PS. openshot works good with new or old other projects. Problem is just with my current main project.
PPS. Here is old working project file http://50.78.53.169/mike_backup.osp
and here is current file with error http://50.78.53.169/mike_current_error.osp
