Are there any reasons why you don't just use master as your upstream
branch. Is it because you want the tarball 1:1 comitted to git?
If you do use master as your upstream no import is necessary. If you
want pristine-tar commits use --git-pristine-tar commit when building or
"gbp export-orig / gbp pristine-tar". This also makes "gbp clone" work
out of the box. This is what I'm doing for my projects.
Also have a look at the (unfinished) "gbp import-ref" in current git.
I'm cc'ing the gbp list since this might be of interest to others.
Hope this helps,
