I built pgadmin3 1.2.1 with wkGTK-2.6.2 on NetBSD/i386 2.0_BETA by
means of pkgsrc-wip, but the resulting binary segfaults on startup:

Program received signal SIGSEGV, Segmentation fault.

This looks like the same crash as that reported in
<http://lists.freebsd.org/pipermail/freebsd-ports/2005-January/019694.html>
The following patch appears to fix the problem. Is it the correct fix?

Use at least 1.2.2, or even better test the new 1.4 beta-1.
If the problem persists, post a fresh stack trace here.
