The first step would be to identify which git command is actually causing it. Can you take your git-sh-prompt and run it step by step to figure out what command is failing?

The next step after that would be to see if we can reproduce it in a reduced test case (with no real data) so we can add a regression test and a fix for it.

so it's a

    cd submodule
    git <command>

that is failing?

Thanks, Stefan
