SWTException when deleting a defect from an execution event.

Using the TPTP-4.5.1-200809160100 build, adding and then deleting a defect from an execution event in the Test Log view causes the following SWTException:

org.eclipse.swt.SWTException: Widget is disposed

Note, the defect is deleted successfully so the only impact to the user is the SWTException in the .log file.
Comment 1 Paul Slauenwhite CLA 2008-10-10 08:01:25 EDT 
Symptom covered by an existing test case.
Comment 2 Paul Slauenwhite CLA 2008-10-10 12:04:25 EDT 
This exception is caused by disposing the 'remove' ImageHyperlink while handling the linkActivated event.  Opened SWT defect #250461.

Note, this symptom is only reproducible in Eclipse 3.4.1. 

Increasing priority since this defect will impact the product's accessibility:

...
at org.eclipse.swt.widgets.Control.getAccessible(Control.java:1022)

Comment 4 Paul Slauenwhite CLA 2008-10-23 07:50:31 EDT 
Resolved by Eclipse defect #250461.
Comment 5 Paul Slauenwhite CLA 2008-10-23 07:51:17 EDT 
Verified in TPTP-4.5.2-200810210100 (Eclipse 3.4.2 M20081015-0800).

Closing.
