Sorry for posting so much ... but its so _annoying_ not to be allowed to
close any file without crashing :(

Still in hope anyone can help,
here I have a completely different backtrace.

 1. open file
 2. close file using context menu (right click at tab bar)
 3. gideon still alive
 4. reopen the same file
 5. close as before
 6. crash

Another idea I had: might there be race conditions involved?
I've got two processors in my SUN boxes ...
