MC log

Original bug: https://bugzilla.gnome.org/show_bug.cgi?id=606660

In this bug, the user tries to import 3 IRC accounts from Pidgin. These 3 accounts uses the same nick and so have the same 'account' property. Empathy starts 3 CreateAccount calls in parrallel. MC seems to fail to assign an unique object path to each account and so crash.

Attaching MC and D-Bus log.
