Description of problem:
Whenever I perform an rpm transaction on my computer, through yum or with rpm
directly, I get at least one error message of the kind;
error: failed to stat /home/daniel/public_html: Permission denied
as is to be expected, with the transaction being run by root and the mount
performed by my user (daniel).
As far as I can tell it doesn't cause any actual failure, i.e. the transaction
proceeds as it normally would, but from reading the code I suspect disk space
calculations aren't performed, and the error messages are starting to fill up my
cron job email (nightly yum).

Version-Release number of selected component (if applicable):
rpm-4.4.2-32

How reproducible:
Always.

Steps to Reproduce:
1. yum install fuse-sshfs
2. gpasswd -a <user> fuse
3. su - <user>
4. mkdir ~/test
5. sshfs <user>@<host>:<path> ~/test
6. exit
7. <perform rpm or yum transaction>

Actual results:
error: failed to stat /home/daniel/test: Permission denied

Expected results:
No error messages.

Additional info:
The attached patch is my half-hearted attempt at fixing it. I imagine it has
unwanted side-effects I did not consider though.
