I'm using Ubuntu Jaunty and Kdenlive 0.7.3 crashes everytime I try to open a project, I changed the video preference from automatic to X11 but nothing happened, any idea?

This backtrace appears to be of no use.

This is probably because your packages are built in a way which prevents creation of proper backtraces, or the stack frame was seriously corrupted in the crash.

Same thing here. Cannot open any project.

I removed frei0r that made the program crash on opening, I can open the program, but still cannot use it.

I reinstalled frei0r and the program wont start again.

I am not a programmer so I cannot help in any other way but reporting.
