Coverity FORWARD_NULL - CID 12451 - plugins/animation/src/extensionplugin.cpp - in function: ExtensionPluginAnimation::paintShouldSkipWindow(CompWindow *) - Dynamic cast to pointer "dynamic_cast <RestackAnim *>(aw->curAnimation())" can return NULL. Passing null pointer "dynamic_cast <RestackAnim *>(aw->curAnimation())" to function "RestackAnim::paintedElsewhere()", which dereferences it. (The dereference happens because this is a virtual function call.)
