Description Anthoine Bourgeois 2009-10-24 19:34:40 UTC 
I merge kdenlive in ~amd64 and its dependencie mlt. I use gnome on day to day but I don't find an application like kdenlive in gnome then I install it.
I have 0.7.6 installed this bug is reproducible every time. 
When I create a clip title, kdenlive crash.
Steps To Reproduce :
1. Open the "create a title" window
2. (optional) Add some text
3. Click on "Ok"
4. Kdenlive crashes

This crash came from mlt (see the trace below):
