Bug#882108: xmonad is almost entirely nonfunctional

[Alexis Hunt]

Package: xmonad
Version: 0.13-6
Severity: important

Dear Maintainer,

I have been using xmonad for a long while, and today upgraded to Buster. While
xmonad worked at first, after making a change to my configuration file, it
stopped working:

1. I can't run xmonad --recompile; it just says "Use Stack!"
2. Previously, I put xmonad in my .xsession and started it like that. Trying to
   do so causes it to fail, again saying "Use Stack!" in .xsession-errors, and
   kicks me back to the login screen.
3. Switching to select Xmonad in LightDM's WM list lets me log in properly, but
   then xmonad crashes after executing the startup scripts.
4. Trying to manually recover it with --replace also says "Use Stack!"
5. Removing my .xmonad directory lets me log in and xmonad does not crash, but
   none of the keybinds work so I cannot open programs, dmenu, etc.

It is, as a result, completely unusable.
