Hi,

There appears to be a problem with Gnus and gnus-summary-refer-parent-article

When I type "^" (gnus-summary-refer-parent-article) I get the error:

   Wrong type argument: stringp, nil

If I type the same key, ^, immediately after, I either get the parent
article (as originally expected) or I get the error:

        No such function: nnregistry-request-group

I set `toggle-debug-on-error' and see in the *Messages* buffer:


while: No such function: nnregistry-request-group
Entering debugger...
Mark set [2 times]
No references in article -4
utf7-encode: Wrong type argument: stringp, nil

Not sure why the first time pressing the key ^ on an article in the
*Summary* buffer always fails and the second time either succeed to
retrieve the parent article or gives me the
"No such function: nnregistry-request-group" error.


Here is the backtrace:

Debugger entered--Lisp error: (error "No such function: nnregistry-request-group")
  signal(error ("No such function: nnregistry-request-group"))
  (while t (signal (quote error) (list (apply (quote format) args))))

If you just eval the following, do you also get the backtrace?

(gnus-request-group "nnimap+aol:INBOX" t)

The definition of `gnus-request-group' doesn't talk about nnregistry at
all, so I'm not sure what this all means.  Perhaps someone who knows
more about the registry could look into this?

Right now I don't get a backtrace, only `t'.

This error doesn't happen all the time, though..

Could you try to determine what makes the bug happen?

More information was requested three months ago, but none were given, so
I'm closing this bug report.  Please reopen if further progress is made.
