Summary

0002267: Segfault whilst deleting clip from timeline

Description

Whilst deleting a clip from the timeline of a video project, kdenlive froze and segfaulted - the clips were a 15 second single image slide in .jpg format which i'd imported, accompanied by a 15 second audio announcement in .mp3 format.

Attached below is the full bug report generated by KCrashHandler, which gave me instructions to report this here, as it was unsupported within the KDE Framework.

Steps To Reproduce

Import 2 clips as described above (1 JPEG (set duration to 15 seconds))
(1 MP3 audio clip @ 15 seconds length)

Place the jpeg on track video 1
Place the mp3 on track audio 1

Play the project once through the project monitor.

Rewind to the start

Delete the image clip on track V1 and confirm when asked

Kdenlive will segfault

Additional Information

This is the KCrash generated bug report (all debug symbols installed) - I was reliably informed by KCrashHandler that this information was very useful, it rated it as 3 stars :)

Notes
(0007128) ttill (developer) 2011-08-02 10:26	Please update to 0.8 and keep in mind that 0.8.2 will be released soon.

(0007132) BarkingFish (reporter) 2011-08-02 14:45	Thanks for that ttill - unfortunately, my distro does not have a release package for 0.8 at this time, so I guess I'm going to have to compile one from source.
