openshot crashes with memory corruption

[XXLRay]

I use openshot 1.4.3 from the bazaar repositories and melt 0.8.8. Openshot crashes when I left-click on a clip on a track. The error messages differ or there is no message at all but here is a new one:

*** glibc detected *** python: malloc(): memory corruption: 0x00007f5e4c13e678 ***

Sorry - my description was wrong. It happens when I left-click on the timeline not on the clip.

[Andy Finch (fincha)]

Have you updated ffmpeg/libav recently? Maybe try those same files in ffplay/avplay?

[XXLRay (xxlray)]

At least I did not update it intentionally. I could by the way work around the problem by removing the speed up clip although it was cut out of a clip where the rest did not throw this problem.
Nevertheless I still have a lot of crashes when I have a preview even without this piece.

[Olivier Girard (eolinwen)]

At first look, you seem to have a problem with libgvfs at this level.
Did you have something connected at the same moment ?

Of course there was "something" connected like my USB keaboard, mouse and backup hard disk.

[Olivier Girard (eolinwen)]

Strange. I don't have that when I crash it and I have too an usb keyboard
and mouse.
Usually, the last item is the cause of the crash.
I don't understand the reason of this crash with the left-click on a track.
Could you give us more details on specifications of this project (project,
files, what do you have make ) ? Perhaps, we could try to reproduce it..

I could sort out the last one. It seems to come from the encoding of some clips. I had several clips directly imported from the same camera but the error occurred for the ones where I increased the speed to 8x. I had done this before in other projects with files from the same camera and don't understand why it was happening now.
As a work-around I used ffmpeg in the command line to increase the clips' speed. Anyway I think that encoding problems should not cause the whole program to crash.

[Olivier Girard (eolinwen)]

Hum! I'm a bit curious.
Could you use Mediainfo using the Text mode on one of this files ?

And now - in a new project - I had a memory allocation error:

...

The memory allocation error even exists for small projects. Currently it's a nightmare. I open the project using the "Recent projects" menu, click on the timeline to find a cut position, make a cut, click on the timeline again to find the next cut and it crashes. Here is the typical output:

Is the next_analyze duration reached thing something bad or the not alligned data? Is there any strace command I can execute to help you find the reason?
