[issue158] Fix for crash with search when packages have an empty description

[Pascal Bleser at Labix Tracker]

New submission from Pascal Bleser <guru at unixtech.be>:

When channels include packages that have an empty description, "smart search"
crashes.
The attached patch solves that issue by more thoroughly checking package
description attributes before electing them as search hits.
