This is bug 597068[1].  The issue appears to have been caused by a
misunderstanding of when the package manager can and cannot solve
circular dependencies, and the fix is likely to be to move
gtk-engines-adwaita from RDEPEND to PDEPEND in gtk+:2, as
gtk-engines-adwaita has a build-time DEPEND on gtk+:2 (not just a
runtime RDEPEND).
