It sounds like some part of the system has crashed. Please:

1. Apply the workaround from bug 994921.

2. Look in /var/crash for crash files and if found run:
     ubuntu-bug YOURFILE.crash
   and tell us the ID of the newly-created bug.

3. If step 2 failed then look at https://errors.ubuntu.com/user/ID where ID is the contents of the /var/lib/whoopsie/whoopsie-id file on the machine. Do you find any links to recent problems on the machine? If so then please send them to us.
