[Kdenlive-devel] Bug Report: Crash on enable/disable audio or video on a track

[socke]

When you enable or disable video or audio on a track, the application 
crashes.
I use the recent CVS version of MLT, FFmpeg and Kdenlive and compiled it 
on amd64 (kubuntu edgy).
To be able to compile MLT, I had to disable the gtk2 module.

This is a backtrace of the crash:
