git-svn dcommit Filesystem has no item

I've been having a problem that I can't find any answers for online.

I'm using git 1.7.3.4 on OSX 10.6 from the installer.

I've got a subversion repository cloned that has a space in the URL. I
put "%20" in the URL when i cloned the repository.

Sometimes when I do a git svn dcommit - usually when I'm going to
commit a new file or (especially) a renamed file it errors out like
so:

git svn dcommit

Committing to http://10.0.0.1/svn/Internal Projects/project/trunk ...
Filesystem has no item: '/svn/!svn/bc/1467/Internal' path not found at
/usr/local/git/libexec/git-core/git-svn line 574


The "1467" is always (I believe) the latest svn commit.

I've already git svn rebase'd before this.

The only way I've found around it is to make a patch and make the
change directly in subversion, checkin with the same comment, and then
rebase my git.

Please tell me somebody has some insight into this...
