Blackbox (0.70 / 2004-09-16, from anoncvs) crashes with following
message when I try to iconify OpenOffice.org 1.1.2 document window:
assertion "hasWindowFunction(WindowFunctionIconify)" failed: file "Window.cc", line
1722
I think the crash happens because OpenOffice has little (transient)
helper window, which doesn't want to be iconified. And when I close
the main document window Window::iconify function wants to close all
transient child windows too.
But because this one helper window doesn't have iconify functionality
allowed the assertion is triggered and Blackbox crashes.

Simple work around:
Change assert from:
assert(hasWindowFunction(WindowFunctionIconify));
to:
assert(hasWindowFunction(WindowFunctionIconify) || isTransient());
xprop for the main and child windows (if needed):
http://gurb.ton.tut.fi/~tkoskine/blackbox/oo.main.window.txt
http://gurb.ton.tut.fi/~tkoskine/blackbox/oo.child.window.txt
And I am running Blackbox on OpenBSD 3.6-beta. OpenOffice 1.1.2
runs remotely via X-protocol from FreeBSD 4.10 (on the same subnet).
Blackbox is compiled using GCC 3.3.2.
I don't know is my way a good way to solve the problem or is
it better to add WindowFunctionIconify flag to every transient
window or should one fix OpenOffice.org.
