the whole test/unittest_compare.py in rql module is marked as broken, find out why

class RQLCompareClassTest(TestCase): """ Compare RQL strings """ @classmethod def setUpClass(cls): raise SkipTest('broken')
All those tests are skipped because they are apparently broken.
It might worth it inspecting them and maybe fixing them.
