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
