MonitorXrandr: Mask a BadValue error on VirtualBox. (1.04 KB, patch)

Description Colin Guthrie 2013-09-05 13:15:57 UTC 
The XRRChangeOutputProperty call will sometimes return a BadValue exception when running under VirtualBox (noticed with the current latest 4.2.16 + kernel 3.9.8).

This is an uncaught exception and results in mutter (and thus gnome-shell) crashing.

I will attach a patch that masks this problem.

I still don't know why it would report BadValue, but this looks good to me.
