compiz crashed with SIGSEGV in unity::switcher::Controller::Impl::GetCurrentSelection()

[JLopeZ]

Crash happened after I re-attached an external monitor and then used Alt+Tab to switch between windows and move those windows to the new monitor (extended desktop).

This was generated using apport. Let me know if something is missing.
