Comment 1 Tim-Philipp Müller 2011-12-28 23:51:30 UTC 
Could you run this (preferably after installing debugging symbols for gstreamer and the various plugin packages):

 $ export G_DEBUG=fatal_warnings
 $ gdb --args /usr/bin/gst-launch-0.10 dvdreadsrc ......
 (gdb) run
 ... wait until it aborts ..
 (gdb) bt
 ... copy'n'paste the output ...
 (gdb) k
Comment 2 Otávio Cipriani 2011-12-29 12:26:47 UTC 
I don't know for sure if I installed all debug symbols, but here is the backtrace:

This looks like bug #640272, though it's hard to say for sure since you don't seem to have debugging symbols for gst-plugins-ugly / the x264enc plugin.

What's the output of:

 $ gst-inspect-0.10 x264enc | grep Version

?

Alright, I think this is a duplicate then. It should be fixed in 0.10.18. Thanks for the follow-up.
