Bug Description
In raring I've found that when directly opening some png files, or somtimes when an application loads png's the Xorg freezes either completely, or sometime allows the mouse to move.
In a specific case, opening the attached png with the intel driver will cause Xorg to freeze but the the cursor will still move, but interaction is futile. System remains accessable over SSH.
The following log is found in Xorg.0.log
(EE) [mi] EQ overflowing. Additional events will be discarded until existing events are processed.
