2.15.x: 'loading theme icon for stock' problem persists...

["Joseph E. Sacco, Ph.D." <joseph_sacco comcast net>]

A common [fatal] error reported by a number of applications in the
2.15.x branch is:

        Gtk-WARNING **: Error loading theme icon for stock: Failed to
        open file '': No such file or directory
        
        GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT
        (object)' failed
        aborting...

Questions:

* Is there a simple work around? 
It is difficult to test 2.15.x with this error in place.

* Any chance that this problem will be resolved any time soon?
I have seen this problem in 2.15.0, 2.15.1, and 2.15.2.
