mwhudson has found a branch (lp:~ubuntu-core-doc/gnome-user-docs/ubuntu-karmic) that reproduces this, but only LP's hosted copy, not the read-only mirrored copy that most users see. He's put a snapshot of the hosted copy at lp:~spiv/+junk/u-k for me. Again, it's likely that Launchpad's mirroring may interfere for most people, but it's certainly reproducible by me now.

The recipe to reproduce is simply "bzr get lp:~spiv/+junk/u-k" — no shared repos or anything else involved on the client! The source branch is stacked on lp:~vcs-imports/gnome-user-docs/master.
