signond crashed with SIGSEGV in SignonDaemonNS::CredentialsAccessManager::customEvent()

[Mattia Rizzolo]

The entire gui stack freezes suddenly, and I restart unity (using `unity --replace`) via a console (tty1).
before I got also a crash of compiz, but I had some trouble with my network, and apport failed to upload the bug report, and, using now apport-bug tells me that the state changed. I have the .crash file (attached), if necessary.

Status changed to 'Confirmed' because the bug affects multiple users.

That version has reached EOL since a while, so it will not receive update. If that issue still exist, report again using ubuntu-bug.
