Hi, Eli.  No, it's not a problem for me at all, now that I figured out
what was wrong.

(Though it wasn't so easy to figure out what it was because there were
no error messages, and I'm not familiar with Emacs internals, so it was
hard to navigate them in GDB.  In the end I found it git-bisecting my
configuration files.)
