Bug #562: CRASH: Dies in CoreGraphics _CGSWindowBounds

Just received this crash report from a user (will attach, pasting excerpt below):

This is occurring upon receiving a piece of cover art from iTunes. Synergy Advance hands the art off to CoreImage so that it can composite a badge for the Dock icon.

Looking at the stack trace I suspect that there is some problem with the image and CoreImage is choking on it; as such there is probably nothing that I can do to avoid this kind of issue.

But you may wish to try one of the newer nightly builds to see if you can reproduce the issue there (all of the Dock icon code has been completely rewritten):
