pkgin loses consistency with pkg_install database

[0-wiz-0]

I'm testing wip/webkit* so I install that from time to time instead of
www/webkit-gtk.

I got pkgin in an inconsistent state.

Here it's already inconsistent, because gnucash is still installed and depends on it:

# pkgin rm webkit-gtk
1 packages to delete:
 webkit-gtk-2.36.8nb29

proceed ? [Y/n] y

I thought that at this point, pkgin should have healed itself, but no:

# pkgin rm webkit-gtk
1 packages to delete:
 webkit-gtk-2.36.8nb29

proceed ? [Y/n] n

pkg_install is correct.

# pkg_delete webkit-gtk
Package `webkit-gtk-2.36.8nb29' is still required by other packages:
      wxGTK32-3.2.10
      yelp-3.32.0nb38
      gnucash-5.15

Why didn't this self-correct when I did 'pkgin in gnucash'?
