Sadly, this backtrace is useless as it lacks debug symbols for most parts.

The backtrace on launchpad.net is for a crash in malloc, which usually indicate
prior memory corruption.

It's possible that a single corruption bug might cause both the malloc crash
and the hang though.

You can try installing debug symbols (same package names, but with a -debug or
-dbg suffix, usually) for all the relevant software (all the gstreamer ones,
glib, glibc, libgstreamermm), and run with valgrind (it'll be slow):

G_SLICE=always-malloc valgrind /usr/local/bin/subtitleeditor >&
/tmp/sevalgrind.log

Then reproduce the bug, and hope valgrind caught something interesting.

You can also post another trace with the debug info installed, it might shed
more light too.
