Exactly; in glib-2.36, g_type_init has been moved to a ctor, which is
automatically called before main(); hence, this setenv is too late now.
Mozilla software is also affected by this, see:
and many others. Firefox et al already use launcher scripts, so adding
one more line won't be a big deal for them.

Given that the only programs which seem to be *practically* affected by
this is our Emacs, and Firefox/Thunderbird/etc. (which we don't have
yet), and using G_SLICE=always-malloc apparently affects performance, I
don't think that would be an appropriate solution.
For now, I think you'll have to add a wrapper script.
