Bug#673428: failing unittests (on stable Debian system)

[Yaroslav Halchenko]

Package: python-quantities
Version: 0.10.1-1
Severity: minor
Tags: upstream

Since happens actually on squeeze   where no official quantities package
available -- minor severity but it still would be nice to have those issues
addressed since no upstream version rquirements seems to forbid use of
quantities in such environment:
