Hi everyone,
I am having some problems with kdenlive on a arch linux distribution: when I start a DVD wizard the window shows up, let me put together all the videos I want in the DVD, but then when I press the "Next" button, it seems to freeze.
I've tried to do a bit of debugging with GDB and what I found is that it freezes on a pthread_join call:
Does anyone have any experience on this?
Thank you
