Unity 2d crashed unexpectedly. unity-2d-shell crashed with SIGSEGV in QDBusAbstractInterface::asyncCallWithArgumentList()

[Jussi M.]

Unity 2d was reported to have crashed after I pressed either the the alt-key or the command key - both were pressed a few times. VMware Fusion. Ubuntu 64-bit.

Expected event: Opening of the run command -dialog or opening of the search-dialog.

Occured event: Unity 2d was reported to have crashed.

Since then: normal behaviour.
