test pickle PDBModels.list corrupted

The Mod/Analyse.py test case fails with:

Traceback (most recent call last):
File "/home/raik/data/py/Biskit/Test.py", line 1220, in test_Analyse

raise PickleError, 'Python pickle %s is corrupted.' % filename
PickleError: Python pickle /tmp/tmpjsKe3o_test_Analyse/modeller/PDBModels.list is corrupted.

The Mod/Benchmark.py test case fails with a similar error.

This looks like the famous 64 / 32 bit problem (works on 32bit platforms).
