Bug: more information on a crash

Hi the list,

In the package KmL (new version, not release yet), the main function 
seems to work correctly but once in a while, R crash (full crash, 
anything link with R is closed and windows ask if it can send a crash 
report). More precisely, when I run it in a loop on 1000 data sets, the 
crash is certain... Is there a way to get more information on what cause 
this?
