Problem with git-svn

I'm trying to use a Subversion repository with Git. I had great success with many repositories except one. This one live since long time and as been migrated from CVS to Subversion.

The current Subversion repository contains multiple projects. Each project is under /trunk. While trying to import the project PROJ:

  $ git svn clone svn+ssh://myserver/trunk/PROJ

I get:

Initialized empty Git repository in .git/
W: Ignoring error from SVN, path probably does not exist: (160013):
Filesystem has no item: File not found: revision 100, path '/trunk/PROJ'
Found possible branch point: svn+ssh://myserver/importfromcvs/trunk =>
svn+ssh://myserver/trunk/PROJ, 48467
Initializing parent: git-svn@48467
W: Ignoring error from SVN, path probably does not exist: (160013):

r9458 = b90789186c85a19a9f32ea6dc8a4259e2eadef67 (git-svn@48467)
        A       file.el

But file.el is not part of this project, it is part of another one on the same Subversion repository. It looks like git-svn get confused at some point. I've been trying to track this down, but since I've never written a single Perl script that's not easy :(

Note that AFAIK each CVS modules have been imported into /importfromcvs/trunk then move into /trunk/<MODULE_NAME>.

r48467 seem ok as a branch point:

<<
------------------------------------------------------------------------
r48468 | svn | 2007-05-09 15:10:54 +0200 (Wed, 09 May 2007) | 1 line
Changed paths:
   D /importfromcvs/trunk
   A /trunk/PROJ (from /importfromcvs/trunk:48467)

Importing module PROJ into SVN.

So I'm looking for hints about the possible problem.

Note that I have tried to reproduce this with a small script (using the same repository structure) but I was not able.

Thanks, Pascal.
