It look like there is an issue with your python installation, have you 
installed some non default python packages. AFAIK Fedora 7 uses python 
2.4, Python 2.5 was first introduced in Fedora 8.

yum should work with both python 2.4 & 2.5, but other python component 
might not.

If you need python 2.5, why dont you upgrade to Fedora 8 ?
