superswitcher segfault

[GoogleCodeExporter]

I'm getting random segfaults from time to time on superswitcher 0.6.  I
managed to catch the backtrace on it finally.  Hopefully this will help
with debugging.

Environment: Ubuntu 7.10 x86 default gnome.  Typically running tilda,
firefox, liferea, xchat, xemacs, pidgin, a bunch of terminals, and lotus notes.

(gdb) set args -c
(gdb) run
Starting program: /usr/local/bin/superswitcher -c

I've just committed revision 33, which should be more robust to things like 
windows
that are "Always on Visible Workspace", and things like Tilda.  If you can 
check out
and build from the latest source, let me know if this latest version helps fix 
the
crashes you've been seeing.
