Developer note: this is related to commit rev29118 and bugreport #22469.
Setting image source in rna_Texture_voxeldata_image_update isn't good idea, it'll lead to crash when there's no image, Source can't be switched from combo-box and this also leads to image disappear when image was created in image editor and then set as source for voxel.
Haven't touched this area before and it's quite late now, so can't provide any useful/tested patch. Maybe tomorrow.

fixed crash, agree that setting this isnt a good idea but this is more of a design issue then a bug.
