Description of problem:
if you try to restore an rpm to its original permissions using --setperms, rpm
exists with a chmod failure.

Version-Release number of selected component (if applicable):
rpm-4.4.2-47.el5.x86_64

How reproducible:
Always

Steps to Reproduce:
1. install package
2. run rpm --setperms packagename
3. watch errors

Actual results:
On each file, rpm throws a chmod error similar to the one below (for httpd)
chmod: invalid mode: `0100644'
Try `chmod --help' for more information.
chmod: invalid mode: `0100644'
Try `chmod --help' for more information.
chmod: invalid mode: `0100644'
Try `chmod --help' for more information.

Expected results:
rpm properly resets permissions to default state.

Additional info:

This is a very useful feature when attempting to repair a system, and should be
fixed.

Appears I spoke too soon. This appears to be more because of the use of
--setugids, not --setperms. --setperms works as advertised. It's --setuigids
which fails with the errors listed above.

UGH... STILL speaking too soon.

Individually each command succeeds.

rpm --setperms httpd ; this succeeds
rpm --setugids httpd ; this succeeds
rpm --setperms --setugids httpd ; this fails with the error chmod: invalid mode:
`0100644'

rpm --setuigids --setperms httpd ; apparently command order matters. This fails
with an incremented (one for each file) list of:
sh: line 356: ch: command not found
sh: line 357: ch: command not found
sh: line 358: ch: command not found
sh: line 359: ch: command not found

It would seem that this is something minor and not escaped properly, though I'm
not sure where exactly.

Turns out this has gotten fixed a long time ago in the rebase to rpm 4.4.2.3:
