Bug when jumping to group in empty topic?

[Emerick Rogul <emerick@cs.bu.edu>]

I'm using the latest gnus from CVS and I have the following in my
.gnus.el:

(setq gnus-topic-display-empty-topics nil)

When I use 'j' in the group buffer to jump to a group that's in an
empty topic (and therefore not currently shown in my group buffer),
the new group and all of its parent topics are displayed at the bottom
of my Group buffer under the wrong topic.

For instance, before hitting 'j', my Group buffer looks like this:

  [ archives -- 0 ]
    [ current -- 0 ]
       [5]    0: nnfolder+archive:sent-mail.2003.gz
  [ e-mail -- 0 ]
    [ personal -- 0 ]
       [1]    0: nnml:inbox
  [ news ]
    ...

After hitting 'j' to jump to nnfolder+archive:sent-mail.2002.gz, my
Group buffer looks like this:

  [ archives -- 0 ]
    [ current -- 0 ]
       [5]    0: nnfolder+archive:sent-mail.2003.gz
  [ e-mail -- 0 ]
    [ personal -- 0 ]
       [1]    0: nnml:inbox
  [ news ]
    [ old -- 0 ]
       [5]    0: nnfolder+archive:sent-mail.2002.gz

This looks wrong; I would have expected the topic "old" (and its
group) to appear under the "archives" topic (this is how I have my
topic layout defined).  Is this a misunderstanding on my part or is
there a bug in gnus' behavior?
