Description of problem:
I installed pure-ftpd and pure-ftpd-selinux on my desktop machine temporarily in order to diagnose an FTP-related problem we were having in our internal company network.  When I tried to uninstall, I got this:

# rpm -e pure-ftpd pure-ftpd-selinux
warning: /etc/pure-ftpd/pure-ftpd.conf saved as /etc/pure-ftpd/pure-ftpd.conf.rpmsave
pure-ftpd not found
error: %preun(pure-ftpd-selinux-1.0.29-1.fc12.x86_64) scriptlet failed, exit status 1

and now pure-ftpd is uninstalled, but pure-ftpd-selinux is not.  In the spec file, I see this:

%preun selinux
if [ "$1" -lt "1" ]; then # Final removal
    semodule -r pureftpd 2>/dev/null || :
    fixfiles -R pure-ftpd restore
    /sbin/service pure-ftpd condrestart > /dev/null 2>&1 
fi

The "service" line fails if the main package has already been uninstalled.  This line should either be allowed to fail, or else the dependency of that script on the main package should be made explicit.

Version-Release number of selected component (if applicable):
pure-ftpd-1.0.29-1.fc12.x86_64

How reproducible:
Always

Steps to Reproduce:
1. yum install pure-ftpd pure-ftpd-selinux
2. rpm -e pure-ftpd pure-ftpd-selinux
  
Actual results:
The uninstallation fails while processing the %preun script of pure-ftpd-selinux.

Expected results:
Complete uninstallation.
