[mrtg] Rateup segmentation fault redux

[Ed Kasky]

I finally had some time to dig a little deeper into my problems with 
rateup.   Being more of a sysadmin than anything else, I had some 
help determining where the fault is happening.  Only now I have no 
idea how to fix it.

If anyone has any suggestions given the strace below, don't hold back ;-)
