#1652: bonjour protocol crashes sometimes
--------------------------+-------------------------------------------------
 Reporter:  ywwg          |       Type:  defect
   Status:  new           |   Priority:  minor

 Keywords:                |    Pending:  0     
--------------------------+-------------------------------------------------
 The bonjour plugin is unstable.  There is no specific action that causes
 it to crash, but it does maybe once or twice a day.  It seems like
 sometimes it crashes when I am receiving an im.

 Here is a backtrace:
