I have a strange feeling that this case (head!=NULL but tail==NULL) should 
not happen, by looking at add_plist(), add_plist_top() and delete_plist() 
in src/usr.sbin/pkg_install/lib/plist.c.

Might be interesting to see in what order / with what args the functions 
above are called. I don't have an environment to test this right now, 
though. :(
