I am using ubuntu 13.10 and just installed libimobiledevice from Software Centre. I rebooted after the install and now I am unable to log in. I get to the login in screen, enter my password for my user name and get stuck at that point. It will not go any further.
My problem seems very similar to this thread as they also installed libimobiledevice.
I would have chimed in on that post but I am new user and not allowed to comment.
