Found the root cause: I was sharing the .purple configuration directory between two Ubuntu installations (symlink between homes), Feisty and Gutsy. When I recreated the Pidgin configuration from scratch in Gutsy, the crashes stopped reproducing.
In more detail, I found that the accounts.xml file from the Feisty installation (also Pidgin 2.1.0) would trigger the crash. -- [gutsy] Pidgin 2.1.0 crashes on the freshly updated libc6 https://bugs.launchpad.net/bugs/130852 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
