That is part of my standard test matrix, works fine.

I test creation of templates and CT on both CentOS 5 HN and a Debian 
Etch HN for all of the following:

    CentOS 4, i386 and x86_64
    CentOS 5, i386 and x86_64
    Fedora 7, i386 and x86_64
    Fedora 8, i386 and x86_64
    Fedora 9, i386 and x86_64
    Debian Sarge, i386
    Debian Etch, i386 and amd64

As I said earlier, the only problem between rpm 4.3 and 4.4 is the 
_db.00? files and they are automatically created if missing the first 
time rpm is executed.  Once the templates are created and before doing 
the tar I delete the files.
