From a valgrind log with piding:

This looks very much like a problem in either liblrdf0 or libraptor,
causing memory corruption. I'll reassign this to liblrdf0 as it's the
next package in the stack ;)

From the valgrind log it seems that pidgin uses libxml for parsing the
XMPP protocol while liblrdf uses libraptor which uses libxml for parsing
RDF files. Now there seems to be some kind of conflict between those,
maybe because raptor overrides some error function from libxml which
confuses pidgin. Maybe it's simply impossible to use libxml directly
from an application that also uses libraptor

In any way there are a lot of memory corruptions here and the crashes
always happen at different places it seems. And I don't think it's a
gst-plugins-bad bug at all as the only thing it does (related to this
problem) is calling lrdf_read_file() with some RDF file.
