bzr status, diff, etc do not work properly after remote push

As we all should know, pushing to a remote branch does not currently update the remote working tree. However, after a remote push, bzr status on the remote machine does not work properly. Basically, bzr status does not show that the working tree is different than the last committed revision, when it clearly is different.

In other words, the following 3 commands should always return the same result, but I have a reproducable case where they do not.
# bzr st
# bzr st -r-1
# bzr st -r-1..

I setup the reduced case below using sftp://localhost for clarity. The problem is in both 0.8.2 and bzr.dev rev 1736.

# alias bzrdev="$HOME/bzr.dev/bzr"

# bzr version; bzrdev version;
bzr (bazaar-ng) 0.8.2
