Sorry, I really should take the time before I write. I can reproduce the 
issue actually:


g.copy raster=geology_30m,mygeol
r.category mygeol rules=- separator=':' <<EOF
217:270:1
405:862:2
910:948:3
EOF
r.category mygeol
217	270:1
262	
270	
405	862:2
583	
720	
766	
862	
910	948:3
921	
945	
946	
948

So, yes, there seems to be a bug in r.category. Please file a ticket.
