bzr repositories are corrupted

[dlh]

There is something wrong with our 0.4 and trunk repositories.

$ bzr check

Bzr bug #855155 looks related.

Jip / ohloh.net discovered this issue. You can see the reply Jip received from them at <http://unk.me/~jip/ohloh.txt>.

I can't reproduce the issue ohloh is having with our svn repo.

(Note: this is on the trunk branch)

The error seems to be from revno 795.1.44. Heres the entry object from where the error occurs (Inventory.add, inventory.py):

    InventoryFile(
        '4612@7d95bf1e-0414-0410-9756-b78462a59f44:armagetronad%2Ftrunk%2Farmagetronad:language%2F.cvsignore',

    )

To reproduce, run "bzr log -v -n0 -r 795..796"

It seems that something went wrong with removing language/.cvsignore

Maybe this http://osdir.com/ml/bazaar/2009-04/msg01667.html and this https://lists.ubuntu.com/archives/bazaar/2009q4/063845.html is related?

version: 2.7.0dev1

I can replicate this bug with the following commands:

$ bzr branch https://code.launchpad.net/~armagetronad-dev/armagetronad/0.4-armagetronad-work
Branched 1579 revisions.
$ cd 0.4-armagetronad-work/
$ bzr log --include-merged -v > /dev/null
bzr: ERROR: An inconsistent delta was supplied involving '<unknown>', '4612@7d95bf1e-0414-0410-9756-b78462a59f44:armagetronad%2Ftrunk%2Farmagetronad:language'
reason: Parent not in inventory.

The two suggested links do not seem to be related. They seem to be about moved files, while ~/.bzr.log for the above command does not show any information on moved files.
