Many of the objects in the Carbon.Qt module are typed as Component (CmpObj) when the QuickTime API documents them as ComponentInstance (CmpInstObj). This makes it impossible to use GetGraphicsImporterForFile and then GraphicsImportGetAsPicture, because the latter is incorrectly expecting a CmpObj while the former is correctly returning a CmpInstObj. Attached is a patch to qtsupport.py correcting the incorrect CmpObj typing, checked by reference to the QuickTime API docs.
