Upstream say this is the wrong answer. Using Gtk without GL is *meant*
to work - the problem is that one of the initialization calls is
unconditional (upstream:
<https://bugzilla.gnome.org/show_bug.cgi?id=775279>) and will abort
if there is no GLX library available.

Workaround: "export GDK_GL=disable". Emmanuele Bassi apparently has
a patch somewhere to fix this better, by probing for GLX with dlopen()
before proceeding.

I think this is important (if not RC), because it also affects the
Debian installer: we don't want to have to build a libgl1 udeb.
The installer could use the workaround though.
