Crash while shifting an audio clip in time when (paused) playback overlaps it

[Mark A. Fox]

Ubuntu 12.04 LTS, Openshot 1.4.3 (from the PPA) and 1.4.0 (from the Ubuntu repository).

Not sure if this is just me or my particular project, but I'm able to repeatably crash Openshot by hitting play, pausing playback while the time-marker is within an audio clip, moving the audio clip a little bit (I'm trying to get the timing right here), then moving the time-marker or hitting play. Restarting Openshot, loading the project and repeating the procedure repeats the crash.

I'm just about positive that I've done exactly this procedure earlier while building the project, so the problem might be due to the mix of stuff going on in the project.

I've tried with mp3, flac & wav files and don't experience any crashes when following the process you describe. Not sure what the problem could be as I can't reproduce it. If it is always with the same clip when you get the crash then maybe try removing it, save the project and then add the clip again and see if that makes a difference.

I understand where you are coming from, and I mean this with the greatest respect to the Openshot developers and, in particular, Andy, but I filed the bug report with the hopes of improving Openshot. A user-workaround to a repeatable crash, doesn't seem to improve the product in any way. I don't mind doing more.

Perhaps it is just a strange configuration or hardware issue with my machine, but I am experiencing similar issues with Openshot becoming unstable as projects grow much beyond trivial. This is a shame as Openshot is a perfect fit in an classroom.

If it would make sense, I could tarball a project that produces a repeatable problem and attach it to the bug report, even if it is just to eliminate my system and configuration as the source of the problem? (Actually, I'm seeing the issue on two different machines now, so I'm feeling better about my hardware.) Maybe the attachment size is a limiting factor here?

If there's no interest by the developers in this sort of thing, perhaps because they are busy in another area of development, I won't go to that effort. Otherwise, I'm happy to contribute in this small way.

Just reorganized the problem project to see how large it is and to prepare it for a developer. Tried to cause Openshot to crash as it did initially...it didn't. Added another audio sample, adjusted it's placement in time slightly, then hit play. Openshot crashed.

I'm thinking that this is perhaps a more general problem than I described. I'm no longer sure that the playback time (help me on my terminology here) has to overlap the sample being moved.
