[STUMP] stumpwm "crashing" X server

[Mehul Sanghvi]

I have talked about this in the IRC channel a few times but so far I
had not been able to solve this.
What happens is the following:

     I start my X session using startx.  I have got stumpwm from the
git repository and built it with clisp.
     At times it will be a few hours, at other times it is pretty much
with a few minutes, but opening/closing
     some dialog boxes will almost certainly crash everything.  When I
say "crash" what happens is that the entire window
     manager crashes, taking down the X session and X server with it,
putting me back at the console prompt.
     There is a backtrace/dump that I can see on the console, but so
far had not been able to
      capture it because you can't scroll back on the console (well
not that far back).

I used VNC today and ran stumpwm under there.  I was able to duplicate
what happens _and_ able
to capture all the output of the backtrace.  I have included the
backtrace below.  If anyone has any thoughts
and/or suggestions, please let me know.  Any help would be
appreciated, and if I can narrow down the issue
let me know.  Applications that I have used which cause this crash to
occur are DBVisualiser (a Java app), Pidgin,
TOra,  PCManFm/Thunar (one or the other or both, can't remember at this point).
