No problem :)

The error has to be coming out of `gnus-get-function', in gnus-int.el.
Right above the spot where the error is signaled, we have a:

(require (car method))

In your case, (car method) is supposed to be the symbol 'nnfolder. I
can't imagine how the function name has been constructed as
`nnfolder-server-opened', yet (car method) is something other than
`nnfolder'. So the place to set a breakpoint would be at the bottom of
`gnus-get-function', maybe you can put it behind a check for
(eq func 'nnfolder-server-opened).

Then we would want to know what the value of `method' is here, and also
where in the startup sequence we are.

Thanks!
Eric
