 We received this log from Gary Su:

 When this happens, the activity fails to launch.  Gary says it is
 reproducable by opening and closing activities (even the same activity)
 for a while.  This crash was from Paint.

 I can't think why GdkEventMask would suddenly be missing BUTTON1_MASK.
 Could it be related to the touchscreen?
