[mv] SOLVED(?) - Saved carts cause internal server error 500

[Ed LaFrance <newmedia@newmediaems.com>]

******    message to minivend-users from Ed LaFrance <newmedia@newmediaems.com>     ******

Well, I didn't really solve it, but in the process of trying to, I found a 
workaround.  Adding this statement to the end of the set_cart routine in 
UserDB.pm makes the problem go away...I really don't know why:

::logError("");

I added this right after "$self->{DB}->set_field( $self->{USERNAME}, 
$field_name, $s);".  When I started the server again, I could save and 
retrieve carts all I want without trouble.  Take this line out and the 
thing bombs again, always on the second sequential call to set_cart.

If anyone has an idea why this worked, I would be happy to hear it.  Of 
course this means the error log will slowly fill up, but I can just 
periodically delete it with a crontab command...
