Comment 0 for bug 380621

We have a subversion repo with about 16000 revisions which appears to work fine both with svn and with an existing bzr-svn branch. I just tried to create a new bzr branch on a new machine (Ubuntu 9.04 Jaunty, using its standard bzr versions), and am getting this error:

bzr: ERROR: base checksum mismatch: 'dfd29a2e55275396552bcf7d083ba632' != '41b36ab118bfc4f0d574041d171c7c93'

This is a showstopper. I can't use bzr on this project until this is resolved. I will have to fall back to plain subversion.

My destination bzr repo (shared but empty) was originally a 1.9-rich-roots, but I also tried with 1.6.1-rich-roots and the result was the same. I can pull up to bzr -r 14579 but attempting to pull 14580 gives this error. There does not appear to be anything unusual about 14580, and I can do svn diff's of that changeset and a couple on either side of it. This leads me to believe it is not a problem with the svn repo being corrupted.

The svn repo in question is not publicly available, but I believe I could provide access to a bzr developer on a limited basis for debugging. I'm a ruby/java programmer so could fiddle with python under supervision, if necessary. This repo has minimal merging, so is mostly trunk with a few release branches. In other words, a simple flow.
