Hi (not subscribed),

git-svn uses $ra->get_latest_revnum to find out the latest revision, but
that can be problematic, because get_latest_revnum returns the latest
revnum in the entire repository, not restricted by whatever URL you used
to construct $ra. So if you do git svn clone -r HEAD
svn://blah/blah/trunk, it won't work if the latest checkin is in one of
the branches (it will try to fetch a rev that doesn't exist in trunk,
making the clone useless).

This change seems to work, sorry it's not a proper diff:
@sub fetch_all {
-       my $head = $ra->get_latest_revnum;
+       my $head = undef;
+       $ra->get_log("", -1, 0, 1, 0, 1, sub { $head = $_[1] });
