I've attached the simplest possible packages to demonstrate the problem.
1. rpmbuild -ba dummy1, dummy2-1mdk, and dummy2-2mdk.
2. rpm -Uvh dummy1-1.0-1mdk.noarch.rpm
now dummy1 is installed
3. rpm -Uvh dummy2-1.0-1mdk.noarch.rpm
now dummy1 and dummy2 are both installed
4. rpm -Uvh dummy2-1.0-2mdk.noarch.rpm
now dummy1 is gone; onldummy2 is installed
Apparently this is only triggered when upgrading an existing package to a
later version (step 4). That's what your test was missing.
The obsoletes tag in dummy1 and the provides in dummy2 are unnecessary to
trigger the problem, but I put them in to better simulate the situation that
seems to turn up in real packages.
If you remove the "Provides" tag from dummy1, the problem goes away. If you
remove the "Obsoletes" tag from dummy2, the problem goes away. If you version
the "Obsoletes" tag so it doesn't match dummy1, the problem goes away.
