Hello,

I'm new to Qt but kdenlive video editor keeps crashing quite a lot with
Qt related traces like destructors after using qDeleteAll. Does anyone
here have a clue what exactly is wrong with kdenlive effects UI
processing?

Kdenlive sources can be browsed from
http://kdenlive.svn.sourceforge.net/viewvc/kdenlive/trunk/kdenlive/src/

And three backtraces can be found below.

Thanks,

-Mikko
