Okay, I had enough time today to finally look into these.

Prior to python 2.5, PyObject_{malloc,realloc,free} and
PyMem_{malloc,realloc,free} were essentially just defines to the system
level functions.  With python 2.5, they instead do some other actions
that are different for each family of functions so that the memory usage
of the interpreter can drop at times.[1]  Hence, inconsistent use ==>
segfaults.

Fixed up libuser, newt and pyxf86config (which were the ones I could
find bugs on).
