I've found a workaround. As the "-d" output suggests, the problem is with the XMPP library, which I am not using (I'm only using MSN and ICQ). I renamed "/usr/lib/purple-2/libxmpp.so" to "libxmpp.no" and now Pidgin starts successfully.
Before this, I tried removing the "gstreamer-0.10-plugins-bad" package, and removing the "/home/<me>/.purple" folder. Neither helped. -- pidgin crashed with SIGSEGV https://bugs.launchpad.net/bugs/393943 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
