Ok, I disabled WITH_MYSQL and left loadmodule "app_python.so" at the end of
all the other loadmodule directive and here is the output:

Now, seeing that key.so module was now failing, which I never saw before, I
put the loadmodule for python ABOVE mi_fifo and key and here is the result:

*snip* thousands of line of the same message

Any ideas at this point ?
