Config dialog seems to crash on RPI#

[bob prohaska]

The configuration dialog box for at least some ports seems to be
crashing on an RPI# running recent -current, with a ports tree that
was updated in the last day. The crash seems only to suppress changes
made, apparently leaving the defaults intact. Make doesn't seem to mind.
Right now uname -a reports
FreeBSD www.zefox.org 13.0-CURRENT FreeBSD 13.0-CURRENT r339680 GENERIC  arm64

An example is security/openssl, but chromium and firefox have behaved similarly:

 [config dialog didn't copy/paste]
                                                                                                   

Segmentation fault (core dumped)

I'm wondering if this suggests a more systematic problem on my system.

Thanks for reading, and any ideas.
