Blackbox @0.70.1 crashes in XQuartz 2.6.1 (xorg-server 1.9.3.902) when LC_CTYPE or LANG is set to some UTF8 value

[Peter_Dyballa@…]

The processes created by the X.org Server, for example X clients mentioned in ~/.xinitrc.d/50-clients.sh, inherit only a minimal environment. This is a rather uncomfortable situation since GNU Emacsen need LC_CTYPE or LANG set to some UTF8 value to function correctly. When I add to that script lines like

export LANG=$(defaults read "${HOME}/.MacOSX/environment" LANG)
export LC_CTYPE=$(defaults read "${HOME}/.MacOSX/environment" LC_CTYPE)

it makes blackbox crash, which is launched from ~/.xinitrc.d/98-blackbox.sh:

echo "98-Blackbox WM"
[[ -x /opt/local/bin/blackbox ]] && exec /opt/local/bin/blackbox
[[ -x /sw/bin/blackbox ]] && exec /sw/bin/blackbox
[[ -x ~/Quellen/blackbox-0.70.1/src/blackbox ]] && exec ~/Quellen/blackbox-0.70.1/src/blackbox

The stack is the same as #24535 (which makes this the third duplicate you've filed).
