Comment 80 for bug 1048059

Thanks Jan for pointing these out. That's a little worrying as this essentially means that programs can't use ACLs. But at least we now know the root cause, so let's make udisks resistant to that.

For the record, this is another consequence of not using /run/media/. At some point I'd like to move to a tmpfs /media (with a symlink, bind mount, etc.), but of course not for a Quantal update.
