Changes (by Quozl):

  * owner:  dsd => sayamindu
  * priority:  normal => low


Comment:

 Symptom is reproducible, but frequency is low, therefore lowering
 priority.

 The error occurs because the window has been deleted by the X server by
 the time the Sugar session asks about it.  The patch prevents the error
 from being fatal, allowing the session to continue.  The triggering
 conditions may occur in normal use; the reproducer is not the only way it
 may happen.

 A backport to 0.84 is desired as it will increase software reliability in
 deployments, especially those that may use windows that are destroyed
 rapidly.
