There is a known bug in php regarding session_start().  The problem is if
*some* application sets the session.save_handler to "user", then the next
call, even by some other applicaion, that assumes its the default of "files"
will crash. Its hard to say "it works now", because its an interaction thats 
difficult to predict. AFAIK, it was still a problem in 4.3.10 as they had
just figured it out. I've never seen the problem (this is on freeBSD mind
you) since adding the ini_set() call before the session_start() as follows:

ini_set('session.save_handler','files');
session_start();

Note that applications like "oscommerce" for one sets this to user, which
is the most common one I know of.
