I'd like someone to explain the meaning of the string in the .po module for Yum:
> Package Object was not a package object instance
Looks like a debug message, but hard to understand if you don't code.
It seems a function was called with a wrong argument.
The function was expecting a package object and received an instance
(or variable) of another class (or data type).
