Olive takes a while to enter a folder with a bzr repository

Bzr version 1.6.1, bzr repository version "format: pack-0.92", Olive version 0.95.0.

When entering the root folder of my local-only repository (so I never push it anywhere, just commit. Personal stuff), Olive greys out for a minute or two. The slow performance is somewhat annoying, and since it doesn't have a progress bar either, it goes against the HIG and leaves the user wondering if it got into an infinite loop or something similar.
