Problem staging file

I'm using vss2git [1] which as the name suggests, converts a VSS source control database to git. It has had a couple of hiccups, but for the most part I've not had too much problems that I couldn't manually fix.... except for this one.

I have a file that refuses to be staged.  The commands are:

    git add -A
    git commit -f d:\tmp\tmp1233.tmp

To override, I've tried to manually add the file and even use the -a switch on commit line, but no joy. The file in question stays firmly in the "Changes not staged for commit" section.

Anyone know why this would be the case and how to fix it?

Thanks,

A
