Rainer, please make sure your mailer doesn't break threading.  I tweaked
the "In-Reply-To" now to return to the original thread on the mailing
list.  Thank you.

Can you please run the same again under strace, e.g.,

  $ strace -o git.trace git config user.email myusername AT xyz DOT org

and send the git.trace file?

Also, please send the icacls output for the directory "bar" and the
directory ".git".

What's weird here is the EINVAL error.  I can't reproduce this on
my machine yet, but if I get more info I might be able to do so.

It's not a permission problem per se.  There's no "Permission denied"
message, just an "Invalid argument".  I just fail to see why this
happens...


Thanks,
Corinna
