Summary: Refcounting crash
Classification: Platform
Product: GStreamer
Version: 0.10.34
OS/Version: Linux
Status: UNCONFIRMED
Severity: critical
Priority: Normal
Component: don't know
AssignedTo: gstreamer-bugs at lists.freedesktop.org

While tracking down that bug, I found that the crash is due to improper
refcounting in gstreamer. Unless I'm missing something, the code path is all
gstreamer. It never hits totem.
See the test here at:
http://p.mecheye.net/refcount/0
Notice how it incorrectly gets decremented to 0 during a message free, and is
then used later. (After its memory has been replaced by various pango stuff)
The gdb commands I used:
