This is probably caused by the removal of the set_child_min_width method from Gtk::ButtonBox in GTK+ 3. In ui/dialog/layers.cpp, we have...
!WITH_GTKMM_3_0 // TODO: This has been removed from Gtkmm 3.0. Check that everything still // looks OK! _buttonsRow.set_child_min_width( 16 ); #endif
I guess the response to my comment in the code is "no, it doesn't look OK"!
