the same problem here, except that I have svn v1.4.6.

The patch in question adds the following line to git-svn.perl's
canonicalize_path():

+       $path =~ s#^\.$##;

which makes an empty string from the path ".".  This is especially
unfortunate for 'git svn info', cmd_info() begins with

        my $path = canonicalize_path(shift or ".");

and from that point everything is ruined, but it boils out only when
it tries to actually open() the empty path.

Removing the mentioned line from canonicalize_path() does resolve this
issue on svn v1.4.6, but I'm afraid it will brake again on svn v1.5.
