KDenLive 16.70.07 Automatic Scene Split Crash GDB report

Comment 4 bryanworsley 2016-04-04 02:16:41 UTC

I'm seeing the same bug testing KDenLive 16.70.07 (from master branch ppa) on Kubuntu 15.10 (AMD 64).  Upon applying Clip Jobs > Automatic Scene Split (with any of the options), it appears that processing commences (although I don't see any progress bar), but KDenLive crashes part way through. KCrash Handler reports a Segmentation fault. 
I've attached an example KCrash Handler trace back report and gdb report (hope I did I right) 
The test clip in this case was a 1080/29.97p lossless (UTVideo-YV12) mkv transcode with multiple scene changes (every 5 seconds or so).

Typo error in last comment and attachment - KDenLive version was 16.07.70,  NOT 16.70.07

Please try with 16.08.1 and close if possible. I tried this with a clip and it completed the job although it created an invalid file in the bin probably because it couldn't do the scene split. If you share you file i can test it further.
