Possible issue with git svn-remote.<name>.rewriteRoot?

Hi All,

my 

  git svn fetch

command just ended abruptly with

  Found possible branch point: file:///home/subversion/boost/branches/unlabeled-1.1.1 => file:///home/subversion/boost/tags/release_1_16_1, 7620
  refs/remotes/trunk: 'file:///home/subversion/boost' not found in 'https://svn.boost.org/svn/boost/trunk'

I am using git 1.7.3.4 and my .git/config reads as follows:

---------<schnipp>---------
[core]
	repositoryformatversion = 0
	filemode = true
	bare = false
	logallrefupdates = true
[svn-remote "svn"]
	rewriteRoot = https://svn.boost.org/svn/boost
	url = file:///home/subversion/boost
	fetch = trunk:refs/remotes/trunk
	branches = branches/*:refs/remotes/*
	tags = tags/*:refs/remotes/tags/*
	branches = branches/*:refs/remotes/*
	tags = tags/*:refs/remotes/tags/*
[svn]
        authorsfile=authors.txt
---------<schnapp>---------

Is this a bug, expected behavior, or...?

Thanks!
