please retest with kdenlive and mlt from unstable, it should be already
fixed?

No. Bug still here.

Sure? Could you please test with kdenlive 16.12.1-3 and mlt 6.4.1-2,
also installing the -dbg packages and send me the backtrace please.


Yes, I install Kdenlive and MLT from Unstable. Here is backtrace:

Application: Kdenlive (kdenlive), signal: Segmentation fault

And does this issue still occurs with mlt 6.4.1-2 and kdenlive from git,
but picking up the Applications/16.12 branch?



With MLT 6.5.0 (build from Git) and Kdenlive Git this issue not occur. 
Same as with Kdenlive Appimage package.
