backtrace

Sigabrt occured in thread 1.

Comment 2 Jean-Baptiste Mardelle 2016-09-05 22:41:31 UTC

Interesting, thanks. Looks like the clip you resized had its start point set to -2, which should not be possible. Do you remember how you resized ? was it a clip in a group ?

Comment 3 carion.nicolas 2016-09-05 23:38:46 UTC

The clip was a music clip. I added it on audio track 1, resized it a bit from the beginning, moved it a bit around and then changed my mind and tried to resize it back to its original size. It crashed at this point

Can you reproduce and provide a minimal example project to reproduce the crash?

I think I might have the same bug. I have a bunch of tracks with clips synced together (4 video clips and an audio clip). There's an SVG mask on one track that uses a transition to apply the mask to a video clip. When I move the start point of one of the tracks to the left, revealing more material that I have trimmed off before - Kdenlive crashes, always on the same length.

I uploaded a complete GDB output with thread apply all bt and system information.

In the freeze frame I see that my clips were resized beyond their initial length.

Kdenlive didn't stop me when I reached the end of the clip when I was zoomed out and crashed, because it allowed the clip to be longer than the assigned video file (I guess).

When I did it slowly while zoomed-in, Kdenlive stopped resizing the clip when I reached the input file start boundary, and didn't crash. I resized the rest of the files with no crash!
