severity 573269 normal thanks Hi, thanks for reporting this bug. This only takes pidgin down because the pidgin developers decided for some reason to deactivate the GStreamer registry updating in a separate process. I filed a new bug against pidgin with a patch to use GStreamer properly and then this crash should be fixed. See bug #578476.
This bug here is still a valid bug but not really critical as it doesn't cause any problems if applications use GStreamer properly. It would be nice if someone could get a valgrind log (with --track-origins=yes) of the actual crash with pidgin. Something in the LV2 toolchain corrupts memory and things later crash randomly. Unfortunately I can't reproduce this here, the LV2 plugin works fine for me :(
