I.e. we have one failing test.

On the other hand

$ python2.5 setup.py test

succeds.

I consider this being critical. Also, after fixing this we maybe could release 0.5.14.1 ?

bc.. I did test it in python2.4 before the release and all tests passed.

I just test it again in a clean pbuilder environment and I am not able to reproduce it:
