Again with git-svn: File was not found in commit

Hello Gits,

I'm looking to migrate [Bricolage][] from Subversion to Git. As such, I'm running `git svn` to create a git repository for the Bricolage repository. I moved the files around in Subversion quite a while ago (the trunk, branches, and tags directories used to be at the root, but now they're under a "bricolage" subdirectory), so there's a fair amount of duplication, but I don't mind that, because I can prune those dupes.

[Bricolage]: http://bricolage.cc/

So I ran `git svn` like so:

     md brictmp
     cd brictmp
     git svn init http://svn.bricolage.cc/bricolage --no-metadata -s
     git config svn.authorsfile ~/Desktop/bricolage_committers.txt
     git svn fetch

After around 30 hours of the fan running full tilt on my MacBook Pro, creating 343 branches (yeah, we have a lot of tags), `git svn` exited with this error:

     bricolage/branches/rev_1_8/lib/Bric/App/ApacheConfig.pm was not  
found in commit
     e5145931069a511e98a087d4cb1a8bb75f43f899 (r5256)

This seemed strange to me, so I had a look at SVN:

     svn list -r5256 http://svn.bricolage.cc/bricolage/branches/rev_1_8/lib/Bric/App/ApacheConfig.pm
     ApacheConfig.pm

So the file *is* there in that revision. I had been running 1.6.1.2, so I upgraded to 1.6.2.2 and ran `git svn fetch` again to see if it would pick up where it left off, but it returned the same error (please don't tell me I have to start over!).

I see that this issue has come up [before][], earlier this year; has there been any progress on it? Is there perhaps something I can do to get this working?
