The segfault appears to be occurring during Python garbage collection.
Debugging this is going to require more information, I'm afraid:

 - Rebuild Python with debugging support ('./configure --with-pydebug').

 - Rebuild the C-extension modules (PIL, PsycoPG).

 - Check the libraries that your Python and the C extensions are
   linked against (via 'ldd').

If nothing jumps out at you after doing this work, then you will likely
need to use 'gdb' to investigate some of the objects involved on the
stack of the setgaulting thread. See:

 http://wiki.python.org/moin/DebuggingWithGdb

In particular, the gdb macros shipped with Python are useful for examing
objects in the C stackframe.
