I've got problems with MovieClipMaterial

When I change the material the bitmap from MovieClipMaterial remains in alt3d engine and is still used.

First i change the material to new one and then I try:
mcMaterial.texture.bitmapData.dispose();

Bu then I get errors every frame: (even when there is another material assigned to the object)

ArgumentError: Error #2015: Invalid BitmapData.
at flash.display::BitmapData/fillRect()
at alternativa.engine3d.materials::MovieClipMaterial/redraw()[G:\works\Alternativa3D\src\alternativa\engine3d\materials\MovieClipMaterial.as:111]

thx
