I'm not really sure when/how/why default-directory becomes nil. It seems to happen in non-file-visiting buffers (e.g. *scratch*, *Backtrace*, any comint buffer, etc) from time to time. I know "from time to time" is vague; I've had a hard time tracking it down. I'm using EXWM (not sure if that has anything at all to do with it) and it seems like it happens when my screen turns off after a period of inactivity. I'm not really sure how/why Emacs would know about that though, so perhaps it's totally unrelated. Thanks, Alex
