It's this commit: https://github.com/stumpwm/stumpwm/commit/8a59c96f340351559f87a39685268e8c15a98e0e The bit at the top, lines 118 to 120. There was something funny about the :key argument of the call to `sort'. I think the reason no one could figure it out was that it didn't make much sense that providing a more complex key to the sort would cause a crash. Yet it did. Or perhaps I've gotten it backwards; at any rate this is the commit, and this is the code section that causes the problem. > > Dave > > Eric Abrahamsen <e...@ericabrahamsen.net> writes: > >> Ernesto Alfonso <erjoa...@gmail.com> writes: >> >>> After I physically remove my external monitor, I run an xrandr >>> command to logically disconnect it.
