this looks a bit strange at first sight, 'values' parameter is NULL and 
should not happen. Besides that, in build_rule() functions there are 
other uses of 'values' before line 439, so the crash should have been 
earlier.

Please send full backtrace of the core, in gdb, run 'bt' command (or 
better 'bt full').

Also, if this reproducible, run:

./kamailio -f ../etc/kamailio/kamailio.cfg -E -dddd

and send the output.

Cheers,
Daniel
