While using HUD: unity-2d-shell crashed with SIGSEGV in QDBusAbstractInterface::asyncCallWithArgumentList()

[Benjamin Geese]

I invoked the hud pressing the alt key but wanted to open the dash. I tried to press escape to close the hud with no success. Instead in the lower right corner of the screen a small text input field appeard and i could type text there instead of into the hud.

The the HUD crashed. Interestingly, the global menu appears a rather strange position in the top bar: somewhat near the center instead of the left corner (see the attached screenshot). Im not sure if this is related and if to fill a seperate bug.
