Description Len DiMaggio 2006-10-18 14:08:55 UTC 
I just noticed this on FC5 with Frysk - built from CVS head 20061018.

To recreate the problem:
1) Bring up Frysk Gui
2) Select 'Debug an Existing Process'
3) Select a process (e.g., /bin/bash) and press 'Open' button
4) The 'Source Code' window opens - close it
5) Repeat steps 2 and 3 - choose the same process
6) This exception is raised:

Comment 1 Len DiMaggio 2006-10-18 14:11:17 UTC 
And - if you specify a different process the second time, this exception is
raised in an infinite loop:

Comment 2 Rick Moseley 2006-11-07 15:47:28 UTC 
Appears to be fixed in cvs head.  Cannot reproduce.
Comment 3 Sami Wagiaalla 2007-02-07 15:05:36 UTC 
reproducable using test3380.py

	* SourceWindow.java: now hides instead of destroys itself upon
	Destroy event. Fix for bz3380.
