I tried that but it doesn't trigger debug-on-error, it's just a prompt
that pops up in the minibuffer.  Normally, I'd wait for the message to
pop up and hit C-G, triggering the debugger.  But with debug-on-quit
toggled on, the message never shows up and gnus silently fails to load
mail from that source.  There is mail in the mail spool, and I also
tried deleting and recreating the spool in case something was corrupted
and causing gnus to choke.
