bzr Assertion error registering parent when updating from svn branch

[Deeksy]

When trying to update a subversion repository, I am continually getting the following assertion error:

bzr: ERROR: exceptions.AssertionError: Tried registering <CachingRevisionMetadat

Is this a public repo, or do you perhaps have a way to reproduce this problem?

[Deeksy (cdekievit)]

It's not a public repo, and haven't had this problem on other repositories
unfortunately (though I don't hook up other repositories to bazaar very
often).
I'll see if I can reproduce it, but I've been using the repository for about
3 months in this fashion, and this is the first time I've come across this
error. If it helps, the subversion version on the server is 1.6.3.

Cheers,
Christian

What sort of changes does revision 9256 contain? Could you perhaps share the "svn log -v -r9256" output ? (perhaps with mangled file names)
