Hi there I have used the GUI script on the wiki (kdenlive_builder_v3.sh) to build a version of kdenlive (ffmpeg, mlt, mlt++) as of a couple of days ago. On loading a project, I often get a crash in libsdl (the project I load contains a lot of clips, cutted from this):

Sometimes kdenlive does not crash, but just hangs. Threads looks like this: Program received signal SIGINT, Interrupt.

() My guess is that it is thread 16 that is hanging. But why? Once in a while, it just seems to "work", and I can actually edit using kdenlive. The best combination seems to be _not_ running kdenlive in gdb, and using the file|open action, never the crash recovery, or open recent options/action. Any advice on getting kdenlive to run (stable) on this box? Its a pretty vanilla kubuntu 7.10, which I would rather not update to 8.04 at the moent. Dual core centrino cpu.
