Bug 20567

Description of problem:
the mageia package of qgis (which is a gis software, i.e. for maps) has an odd dependency on python-biopython-sql (why???), which leads to a tail of 30MB of dependencies that shouldn't be required for a gis package.

How reproducible:
always

Steps to Reproduce:
1. try to install qgis via urpmi
2. see how the dependencies list is bloated, especially via its odd dependency python-biopython-sql which in turn requires even wise2, a DNA/protein sequence software:
---
# urpmi python-biopython-sql
To satisfy dependencies, the following packages are going to be installed:
  Package                        Version      Release       Arch
