A comment on the bug report on the pidgin website suggests that this is a server-side issue.
Apparently the server has stopped handling a certain MSN protocol version MSNP15 (as used by pidgin/purple)? The clients that are continuing to function are using earlier protocol versions, or fall-back to previous protocol versions (as in the case of the official clients). -- Unable to retrieve MSN Address Book https://bugs.launchpad.net/bugs/316252 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
