pkg_delete segfaulting after upgrading to 7.1

[Ross Penner]

I've recently upgraded my system to 7.1Stable. While upgrading my
ports, pkg_delete spontaneously ceased functioning. Some of the ports
were upgraded successfully so pkg_delete must have worked at some
point. I'm sort of a novice so I'm at a loss as to how to go about
diagnosing and fixing this problem.

here's an example below:

rosbox# pkg_delete -f gpgme-1.1.5_1
pkg_delete: package 'gpgme-1.1.5_1' is required by these other packages
and may not be deinstalled (but I'll delete it anyway):
seahorse-2.24.1_1
Segmentation fault (core dumped)
