Yes, I get the same result with `B c'.  What seems odd is that I see two
different imap backends in my buffer list.  My ~/.gnus file includes:

  (setq gnus-nntp-server "news.sunsite.dk")
  (setq nntp-authinfo-function 'nntp-send-authinfo)
  (setq gnus-select-method '(nntp "news.sunsite.dk"))
  (setq gnus-secondary-select-methods '((nnml "")
                                        (nnimap "gmail"
                                                (nnimap-address 
"imap.gmail.com")
                                                (nnimap-server-port 993)
                                                (nnimap-stream tls))))

Completion offers both `nnimap:gmail' and `nnimap:imap.gmail.com' as a
valid `B c' destination, but they both respond that the newly created
imap buffer has no connection when I move or copy messages from an nnml
source folder.

Other imap operations seem to work fine though, e.g. all the following
work fine:

  - copying messages from imap folders to local nnml folders
  - moving messages from imap folders to local nnml folders
  - getting new messages into imap folders by typing `g'
  - flag updates when I modify messages through gmail's web interface
    and type `g' in gnus

I can even see messages marked in Gnus with '!' as starred messages in
the web interface of Gmail, and when I unmark them in Gnus and type `g'
they get unstarred in the web UI too.

Whatever the problem is with `B c' and `B m' it seems specific to using
an imap folder as the destination of the messages.  As a source nnimap
folders seem to work more than fine.  I noticed that nnimap access is
now blazingly fast too.  I started using Gmail's imap access method only
because it's now very very fast to access the messages from Gnus too :-)
