Description of problem:
User has the "talk" package installed, and tries to install the "talk-server"
package. The install of "talk-server" uninstalls the "talk" package
(and vice versa).

Version-Release number of selected component (if applicable):
talk-0.17-17
talk-server-0.17-17

Steps to Reproduce:
1. rpm -Uvh talk-0.17-17.i386.rpm
2. rpm -Uvh talk-server-0.17-17.i386.rpm
3. rpm -qa|grep talk
    
Actual results:
talk-server-0.17-17

Expected results:
talk-0.17-17
talk-server-0.17-17

Additional info:
The problem is that both talk and talk-server packages have "Obsoletes: ntalk",
but also "Provides: ntalk". Thus talk obsoletes talk-server and vice versa.
The problem is not only in 8.0, but also in the latest "phoebe" beta.
