You may want to debug it further (see http://wiki.nginx.org/Debugging), 
but please note that MaxMind's GeoIP library (the one which geoip 
module uses) segfaults on incorrect/corrupted database[1].  
Checking if your MaxMind's database isn't corrupted is a good idea.

[1] And this is one of the reasons I recommend using geo module 
instead and always wonder if people use geoip.
