Description Milos Kleint 2001-01-02 16:33:45 UTC 
Here's a stacktrace of an exception I got when changing workspaces from GUI to
Editing. I was not able to reproduce it later. Visually the Explorer and
SourceExitor were blank, with a question mark at the Title of the windows.

(I worked with FFJ20 Build 1160)
