Occassional Gnus posting problem

[nyc4bos@aol.com]

Hi,

I sometimes experience an occassional posting problem that I'm trying
to track down.

After composing my post, I hit C-c C-c `message-send-and-exit'.

I then see a message that says:

  gnus-get-function: No such function: nntp-request-create-group

I then still see the "*unsent*" buffer.

Not sure if it went through, so I hit "C-c C-c" again.

I then see:

  message-send: Denied posting -- multiple copies

So I guess that means it went through (I'm still waiting to see
if the message I tried to send ends up on that newsgroup -- it
hasn't so far) even though the "*unsent*" buffer did not turn
into a "*sent*" buffer.

I did not see the "No such function" error the second time.

How can I track down the "No such function" error?

I'm using Gnus from bzr on December 14th, 2010.

Thanks.
