[crossfire] Crash on Skud bank coin exchange

[James Lopeman]

For useful information you need a core dump 

ulimit -c unlimited

crossfire: Modules/gcmodule.c:276: visit_decref: Assertion `gc->gc.gc_refs != 
0' failed.
Aborted (core dumped)

now lets look at the core file -> gdb /usr/bin/crossfire ./core.26508

then use -> debuginfo-install crossfire-1.11.0-1.fc10.x86_64
( gdb will spit several of these out at your to install untill your kit is 
good)

when gdb quits whining about missing debug packages .... 

type bt
