[ale] rpm bug

[ChangingLINKS.com]

What is the deal with rpms? 
On several occasions, I have installed a package using rpm -i or rpm -U.
Then, if I try to do rpm -e the results is that the "package is not installed"
Finally, when I do rpm -U or rpm -i of the same package, it says "package 
already installed"

Can someone help me understand HOW that can happen so that I won't be so 
frustrated with that aspect. (We will skip the debate on whether or not this 
is a bug or a weakness or not this time.) It seems like the other systems of 
installation that I have used are more reliable - but take more keystrokes.
