According to the gstreamer guys this is most probably caused by a
alignment issue with the altivec optimizations in mpeg2dec. Buffers have
to be aligned in a specific way IIRC.

So this is either a gst-plugins-ugly0.10 or mpeg2dec bug but definitely
no thoggen one.

In Ubuntu this does work on altivec enabled PPCs as they have altivec
support in mpeg2dec disabled. Can you please try to rebuild their
mpeg2dec package[1] on sid and try to reproduce the crash?

Also could you please try running
gst-launch-0.10 playbin uri=file:///path/to/file.mpg
and
mpeg2dec -o x11 /path/to/file.mpg

Best would be both with gdb to provide a backtrace and if possible also
with valgrind.

A probably related bugreport is this one:
