Public bug reported:
Ubuntu 21.04 (Canonical Gnome Desktop not flavour). Installed openbox
(3.6.1-9+deb11u1) and lxappearance (0.6.3-1) from standard repos.
Launching immediately segfaults.
Rebuilding the package still segfaults.
It seems to be having issues parsing:
/usr/share/icons/gnome/index.theme
/usr/share/icons/DMZ-Black/index.theme
These files look normal and have correct permissions.
I added a small hack to src/icon-theme.c to ignore these files and
lxappearance now works correctly but is missing these themes.
