This ascertains that the GUI is innocent :)

That said, lets see how we can track this down.

I've never seen the bt output.  Re-reading your message it seems
that you got a sane stack trace -- just the symbolic information
for the portions that are inside the Tk DLL are missing, right?

(Maybe you should post the bt output)

In the past, I had to manually load the DLL symbols in gdb.
After making sure the DLL compiled with debugging symbols
was the only one around and after stopping somewhere after
it was loaded, I used the add-symbol command to load the
DLL symbols in.  After that was done, the backtrace had
all symbolic info on it.

You'll need the load address of the dll.  The syntax is:

add-symbol filename address
