This simple... from the first bug report I got the impression that
the problem occurred in the Padre test suite.

I am not using NetBSD either, and I might say the same thing :-)
anyway, I'm currently installing NetBSD in a VM. I'm not sure when I
will be able to look into the crash; keep in mind thath Wx is never
going to pass any tests with display unset, the best I can do is to make
it fail without a crash.
