I've gotten the same kind of error several times recently on typing `q'
in the Gnus *Group* buffer.  I haven't gotten a full backtrace, so I've
only seen the top wrong-type-argument error message, which is the same
as yours.  I think I've only gotten this when there's a live *Summary*,
but I can't reliably reproduce it.
