Do you really mean ".m"? Don't you mean ".psp, how else can you use  
"sid.psp"
as file name?

All I can suggest then is to look for the file:

   /tmp/mp_sess.dbm.db

or something named similarly. I don't think it is meant to have extra  
".db" extension
but on my Mac there is one for some reason.

This is the DBM session database. It may have somehow got corrupted.  
If you don't
have a main Apache process that is still trying to use it, remove it  
and start over.

You could also put in your Apache configuration:

   PythonOption session_dbm /tmp/mp_sess_test.dbm

Then return your test. Because it will be a fresh database, if it  
works, may again
show that default database is corrupt.
