This is because stumpwm restarted due to the error.

This is unfortunate. stumpwm should cleanly restart in the event of an
unhandled error. If this happens again try running strace on it to see
what it's doing. Also see if it's using 100% of the cpu.

Have you tried this with clisp?

It appears as though this could be a bug in portable clx. Can boot
mathematica in another wm (ratpoison?) and run:

xprop -id <mathematica window id> WM_CLASS

you can use:

windows %t %i

in ratpoison to get the window id for each window.

When I run the xprop command on my emacs I get:

address@hidden:~/src/stumpwm.git/contrib$ xprop -id 8388796 WM_CLASS
WM_CLASS(STRING) = "emacs", "Emacs"

But I'm hoping something unusual will be displayed for the mathematica
window. With that value hopefully we can come up with minimal
steps to reproduce and discover the source of the error.
