[Freeciv-Dev] (PR#13879) pubserver 2.0 crash in DB code

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

<URL: http://bugs.freeciv.org/Ticket/Display.html?id=13879 >

This crash is in the database code that isn't available in CVS.  In fact 
I'm not sure it's publically available at all (probably a violation of 
the GPL).  Anyway, I can't fix it.
