Hi,

I just got the same problem after reconfiguring a machine (using
guix-home, but I'm not sure if it is relevant). It only happens when
I try to load extra modules from the ".stumpwm/init.lisp" file.

It looks like the configuration indicating where to search for the
compiled Common Lisp files (ASDF's source-registry and
output-translations) is not taken into consideration by Stumpwm
anymore... so it tries to recompile them in the wrong place.

As a workaround, replacing:
  exec stumpwm
by:
  exec sbcl --no-userinit --non-interactive --eval '(require :asdf)' --eval '(asdf:load-system "stumpwm")' --eval '(stumpwm:stumpwm)'
in my ".xsession" file seems to work...
