This crashes on a half-downloaded matroska file. I'm guessing this is not
reproducible ?

Seems to crash here:
http://cgit.freedesktop.org/gstreamer/gst-plugins-good/tree/gst/matroska/matroska-demux.c?id=b26897dd84ac9b09e7d262989a75984aab0bdc91#n2397

So in other words: buf is NULL here (as the SegvAnalysis suggest as well).


This may be caused by one of these goto resume (after buf has been freed and
set to NULL):
