Description of problem:
kdeartwork-extras contains 2 BuildRequires which end up in the description of 
the -kxs subpackage:
BuildRequires: kdebase-devel >= 6:3.5.6
BuildRequires: libart_lgpl-devel
BuildRequires must be listed before any Summary tags. They are also per 
package, not per subpackage, so they have to be listed before the subpackages. 
The first one is a duplicate (it's also listed at the correct location), but 
the libart_lgpl one is rendered useless by this mistake.

Version-Release number of selected component (if applicable):
kdeartwork-extras-3.5.6-2.fc6

How reproducible:
Always

Steps to Reproduce:
1. Look at the description of kdeartwork-extras-kxs.
  
Actual results:
BuildRequires in the description.

Expected results:
BuildRequires in a place in the specfile where they're actually used by 
RPM. ;-)
