gnome-terminal leaks memory on startup after call to g_listenv

gnome-terminal leaks memory on startup because it calls g_listenv without freeing the resulting list of strings. Per the docs, this list must be freed:

http://developer.gnome.org/glib/2.32/glib-Miscellaneous-Utility-Functions.html#g-listenv

g_listenv(): Returns: a NULL-terminated list of strings which must be freed with g_strfreev(). [array zero-terminated=1][transfer full]

Here's the valgrind report with the leak:
