Here it is:

The debugger window showed up when I pressed C-c C-c to send the message
I had been writing.  I had to quit gnus and close the emacs frames to be
able to write a message again, though I didn't quit the emacs daemon
process.  Weird ...

BTW, since it may be related, I'm seeing drafts accumulating in the
drafts folder.  It's as if they aren't always deleted when the message
is sent.  I have a habit of automatically pressing C-x C-s somewhat
frequently I developed about 20 years ago when it was much more needed
than nowadays. Perhaps gnus doesn't like that very much? ;)

Hm, yes, the message I had been writing still has an (outdated) draft in
the drafts folder from saving it while writing it.
