           Summary: segmentation fault on redraw after removal of uiitem
           Product: Moonlight

          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: plugin

If a UI item is removed from display, a segmentation fault can be generated
(occurs roughly every third time on my test)
The UI item test with has some http request data displayed in it.... should not
effect it... it was made visible then invisible. The UI item was dynamically
created just prior to display, dynamic popup style of functionality.

The stack trace associated with the fault is:
