>Description:
gpart fails to correctly create/modify GPT entry partition types and sets it to "!00000000-0000-0000-0000-000000000000" or leaves it unchanged.
Full problem log bellow.

>How-To-Repeat:
localhost# gpart create -s GPT ad4 
ad4 created 
localhost# gpart add -t freebsd-ufs ad4 
ad4p1 added
localhost# gpart show ad4
=>      34  15038397  ad4  GPT  (7.2G)
