Just to make it clear: these functions are new in GLib/GIO 2.18. I've
imported them into the Thunar source code yesterday so that Thunar
should build and run fine with GLib/GIO 2.16.

However, GTK+ 2.14 introduces a few APIs GTK+ 2.12 was missing for
better interaction with GIO. Here are two examples:

  - GtkMountOperation (very important for asynchronous and
    interactive mounting)
  - gtk_image_new_from_gicon()

GtkMountOperation is used everywhere inside Thunar so I'd consider it
important. As a consequence, I'd vote for GTK+ 2.14 and GLib 2.16
(which by coincidence also are the version that correspond to each
other, unlike 2.12/2.16 ... I think).
