Quassel IRC

I don't know exactly how to reproduce this bug, but my quasselcore crashed when a user tried to create a network. Here's the log (I didn't have debug messages enabled at the time):

After the crash, the assignment between identities and networks was messed up in my account (not the one that presumably caused the crash). I had two identities, with one only in use by one network, and that assignment "shifted" after the crash. It wasn't critical in my case, but this could be quite annoying or embarassing.

Also, the Version field in this bug tracker doesn't allow me to select my version of quassel, so that field contains garbage.
