Bug-Report git-svn Empty Repository

hi,

I just tried to replay a stack of patches into a fresh svn
repository. The repository was created in an empty state
(revision 0). It could be checkout out fine using git-svn, but
trying to do git svn dcommit or git svn rebase fails, as $url
does not get initialized in git-svn:410, I think extract_metadata
fails.

I'm using "git-svn version 1.5.4 (svn 1.4.5)".

regards,
Jan
