aqemu crashed with SIGSEGV in Device_Manager_Widget::on_actionProperties_triggered()

[Shawn Kovalchick]

Crashed while trying to start Windows VM. Had enabled spice, but got an error message indicating that spice was not available in the current build. I have since installed sice, but continued to get the message, so I disabled spice.

I'm getting the seg fault on 0.8.2-2 in Quantal on AMD64 as well, but at startup. As a FYI, looks like it's happening in Fedora too so might be an upstream issue:
