Warning: Unable to create "trees" RDF storage.
Performance can be improved by upgrading librdf.

ERROR: Caught a segmentation fault while loading plugin file:
/usr/lib64/gstreamer-0.10/libgstlv2.so

Please either:
- remove it and restart.
- run with --gst-disable-segtrap and debug.

Expected results:
Pidgin should start without complaint.

Additional info:
removing (or mv-ing) the gstreamer file will kind of "solve" the problem because pidgin will be able to start without any warning nor error.
# mv /usr/lib64/gstreamer-0.10/libgstlv2.so /usr/lib64/gstreamer-0.10/libgstlv2.so.back
