Oliver thanks for your patience, I'm learning a few things regarding
python these days :-)

OK we've downgraded to PIL 1.1.6, this is my easy_isntall.pth file

import sys; sys.__plen = len(sys.path)
./mapproxy-1.0.0-py2.6.egg
./pastescript-1.7.3-py2.6.egg
./pastedeploy-1.3.4-py2.6.egg
./paste-1.7.5.1-py2.6.egg
./pyproj-1.8.9-py2.6-win32.egg
./isapi_wsgi-0.4.2-py2.6-win32.egg
./pil-1.1.6-py2.6-win32.egg
./pyyaml-3.09-py2.6-win32.egg
import sys; new=sys.path[sys.__plen:]; del sys.path[sys.__plen:];
p=getattr(sys,'__egginsert',0); sys.path[p:p]=new; sys.__egginsert =
p+len(new)


There's a tool to see what's going on for Windows called win32traceutil
so now I can see the complete trace of 500 errors

It seems something with PyYAML but if I open a python console I can
import yaml without any problem (for example using yaml.dump({''name':"me"})

It seems I haven't learned enough anyway :-S
