Here is last few lines from terminal where OpenHot was run:

Hi,
what is your version of Openshot ? 1.1.3 or 1.2.2 ?
If it is the first version, check all your dependencies like it is saying here : http://openshotusers.com/forum/viewtopic.php?f=12&t=372
We have also forgotten the frei0r-plugins and it can explain this situation. It is resolved on the last version.
Thanks.

I use version 1.2.2
I had check your link and check my version of melt
MLT melt 0.4.4

So I did
sudo apt-get remove openshot
sudo apt-get clean
sudo apt-get purge
sudo apt-get autoremove
sudo apt-get install openshot

AND now I have:
MLT melt 0.5.4

Maybe this was MY problem :)
I did distro upgrade from Ubuntu 9.10 and my MELT package didn't upgrade for some rison...

I will check now how Open Show work and report here in few days.

[Arkadius (arkadius)]

After I reinstall openshot I have error message:

OpenShot started to work.

[Olivier Girard (eolinwen)]

Perfect, if it is working and thanks for the feedback and to have persevere.

[Arkadius (arkadius)]

Bug STILL exists

[Dan Dennedy (dan-dennedy)]

Arkadius, still crashing with the _same_ error? If so, which one?
A single bug report for _any_ crash is useless. To never crash is a goal, of course; not all crashes are the same bug. We need to know the steps to reproduce the crash.

[Arkadius (arkadius)]

It is look like app is randomly crashing.
I can't find common cause.

I can describe the work.
I imported 1 episode of some serial, about 300MB size
I also imported 20 short WAV files and I cut scenes from AVI and add sound from WAV files.

See JPG attachment

Most common operations are cutting video, resizing and playing preview.
There is a lot of WAV files in the backgroung.

Thats all.

Let's focus on some kind of errors.

I two times crashed Openshot:
I opened project
Clicked Play preview
moved a little WAV file
and clicked play againg which should stop preview
and after this app crashed.

See attachment.

[Olivier Girard (eolinwen)]

Could you update your version of MLT, she looks to be the 0.5.4, the actual (i.e. 0.5.10) is better and you have here more explanation for his instalaltion.
If the problem is always present, and like you have a segfault error, could you use this method for having more details about her.

Thanks.

[Olivier Girard (eolinwen)]

Thanks.
First, do the upgrade of MLT (i.e. 0.5.10) and try again.
Second. How have you install Openshot ? the official repository or with the PPA ?
I asked this because i have a feedback for somebody who was some problems with the offiicial repository and none after remove it and re-install it by with the PPA.
So, it can explain it perhaps.

[Arkadius (arkadius)]

Yes I installed Openshot via the PPA.
See post #5
> So I did
> sudo apt-get remove openshot
> sudo apt-get clean
> sudo apt-get purge
> sudo apt-get autoremove
> sudo apt-get install openshot

And after this I have version 1.2.2

I updated MLT:

I have no idea now; I don't understand why he marks you a mp in the output for a wave file.

[Andy Finch (fincha)]

As this is an old bug report, please can you let us know if this is still a problem using the latest versions of OpenShot & MLT.

[Arkadius (arkadius)]

You can close this Bug.
I installed new Ubuntu 12.04.1 x64.
