Bug report about server-ensure-safe-dir

I got a bug report on about server-ensure-safe-dir which I think might
reflect a general problem on w32. It looks like file ownership and
roaming profiles are involved.

Could someone who knows more about roaming profiles than me please have
a look at this? The bug report is here:

Scroll down to the end of it, just before the "Problems" header.
