wxWidgets Debug Alert assert "sizeNew == -1"

On OSX, currently version 1.18.1_0+postgresql92, installed using macports, I get the attached error message frequently.

I have been assuming that it's a known error that will get fixed someday, so I've been pressing "cancel" and carrying on for quite some time now, certainly through multiple versions of PGAdmin, surely back to 1.17 at least.

It occurs to me, after all this time, that perhaps this is something unreported? It's not unique to one machine -- I get it on multiple machines.
I don't see it here http://www.pgadmin.org/pgadmin3/bugs.php

Should I be filing a bug report or something?
