msysgit git-submodule: "Unable to fetch in submodule path ..."

Hi!

This is with msysGit 1.6.3.2.1299.gee46c

I am having some problem when checking out a large project with many 
submodules. After cloning the superproject, doing a git submodule --init 
will fail with a "Unable to fetch in submodule path '...'" for one specific 
module (does this on all machines that we have tried it on). I cannot see 
any error messages from git-fetch itself:

   [...]
   Initialized empty Git repository in c:/Users/peter/src/foo/bar/modules/foo/.git/
   remote: Counting objects: 14752, done.
   remote: Compressing objects: 100% (5036/5036), done.

   Resolving deltas: 100% (9278/9278), done.
   Unable to fetch in submodule path 'modules/foo'

If I enter the modules/foo manually and enter

   git reset --hard

or similar, everything works fine, and I do have the complete history.

Looking at the code for git-submodule, it seems to suggest that git 
submodule is calling git-fetch without parameters, and checking the return 
value from it. It does, as indicated above, not seem to return any errors.

I tried adding a "-v -v" to the git-fetch command line in git-submodule, and I 
see that it does terminate early. With the other modules, I get a list of 
all the cloned branches and tags. But for this module, it stops as above. I 
get some additional debug output, but can't quite say it helps me much:

   Initialized empty Git repository in c:/Users/peter/src/foo/baz/modules/foo/.git/

   Marking 76b96bfecc0d47013dd1fca1a555f12074eca814 as complete
   Unable to fetch in submodule path 'modules/foo'

The string "Marking %s as complete" seems to stem from 
mark_recent_complete_commits() in builtin-fetch-pack.c. The other messages 
seems to stem from do_fetch_pack() in the same file, so it gets there and 
not further. I cannot seem to find any exit point.

Does anyone know how to continue debugging, or know what might be going wrong?
