Hi David,

I first tried "git update-index" but it didn't work. However "git
update-index --refresh" seems to fix our problem.
I didn't get why "--refresh" is needed thought, I'm really not
familiar with the caching aspect of git.
Anyway, I think that this fix is what I need right now.

Thanks,
Chris
