Is WRI going to fix the problem? It is likely caused by executing
Needs (or Get) on Graphics`FilledPlot` somewhere inside the
Graphics`InequalityGraphics` package. One "right way" to do that is to
put Graphics`FilledPlot` in the list of other (needed) packages in the
BeginPackage statement of Graphics`InequalityGraphics`.
