Bug#545736: python-gst0.10: SIGSEGV with my small python Ogg/Theora encoder

Package: python-gst0.10
Version: 0.10.16-1
Severity: normal

Hi,

I am a complete beginner in gst programming, but I believe a python module
should not segfault, thus the bugreport.

My small Ogg/Theora encoder attempt is attached.

And here is the backtrace. Feel free to ask for more info.

Cheers,

Alex
