Converting a directory to submodule

Dear list,

I'm having some trouble when I change an existing directory in a project into a submodule. After pushing this change to the origin, I can no longer pull into any other projects. I can, however, clone the origin without problems.

These are the steps I take to change the dir into a submod:

rm -rf /submod git commit -a git submodule add git://abc/submod submod git commit git push

But then attempting to pull this anywhere else results in a half-completed pull, and dies with the error:

fatal: cannot read object bb138891993fdeb3dbfcb41fe8c2a4693676f8fe 'submod~564e58282ce575db34b6f249a42b1ea59f56efd3' Merge with strategy recursive failed.

Like I said, though, a fresh clone works fine. Am I doing something wrong in my push, or is this a bug?

Thanks, Paul Sadauskas
