By installing the msn-pecan package and readding my msn accont in pidgin and choosing 'wdl' instead of 'msn' everything works fine. I installed msn-pecan by writing:
sudo apt-get install msn-pecan -- 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
