I'm trying to use git-svn to clone a repo that has sub-branches and sub-tags

The SVN layout is like this:

branches/user1/workitem1 branches/user1/workitem2 branches/user2/workitem1 branches/user2/workitem2

tags/v1.0 tags/v1.1 tags/debian/v1.0-1 tags/debian/v1.1-1 tags/debian/v1.1-2

In git, I would like to have branches with the same names, e.g.

branches/user1/workitem1 branches/user1/workitem2 branches/user2/workitem1 branches/user2/workitem2

and tags like this:

1.0 (notice I don't want to keep the v1.0, drop the v) 1.1 debian/1.0-1 debian/1.1-1 debian/1.1-2

However, if I run

git svn clone \
   -T trunk \
   -t tags \
   -b branches \
   https://flactag.svn.sourceforge.net/svnroot/flactag \
   flactag-git1

I don't get any of the branches or tags, and I get numerous warnings like this:

W: -empty_dir: branches/d_pocock/autotools/HTTPFetch.cc
W: -empty_dir: branches/d_pocock/autotools/HTTPFetch.h

I have the impression that git-svn does not like the repository layout, and it is not clear from the manual page how to make it work. Can anyone share any advice about this?
