Hi all,

I have been using kdenlive for quite some time and I recently installed it on a fresh installation of Linux Mint 13 (Maya). Now I cannot render anything. I tried adding a 5 second color clip and rendering it to mpeg-2 just for a trial. Here is the track-back I got:

Rendering of /home/statik/kdenlive/untitled.mpg crashed

Mint 13 dates back from end of spring, a period around which serious memory problems appeared temporarily in MLT (version 0.8) + Kdenlive (0.9).
Situation was much improved during summer with MLT 0.8.2 and Kdenlive 0.9.2, maybe try to upgrade to these versions (you may use sunab's ppa).
