>Description:
	After using the feature which allows the creation of slices and 
partitions to be undone within gpart, deleting a freebsd partition results in 
geom printing a large negative number instead of "1". 
>How-To-Repeat:
gpart create -s mbr -f x da0
gpart add -t freebsd -f x da0
gpart create -s bsd -f x da0s1
gpart destroy da0s1
gpart delete -i 1 da0

A log of the output is attached.
>Fix:
