Dock issue causing log pollution when using Spaces

[RJVB]

An issue exists in VirtualBox's handling of the Mac GUI that causes a huge numbers of kCGErrorIllegalArgument errors to be logged by the Mac OS X Dock each time one changes Spaces. This happens regardless of whether I set the VM Dock icon to reflect the VM screen or not, whether I'm in seamless/auto-resize/fullscreen mode or not.

Here's what I copied from system.log after going back and forth twice (4 Space jumps): Nov 30 10:39:14 portia Dock[217]: kCGErrorIllegalArgument: CGSSetWindowTransformsAtPlacement: Singular matrix at
