Good to hear. No wait, that's bad. Any idea what's causing it?

For some unknown reason, that isn't working. It dies while executing

- (void)runModalPrintOperation:(NSPrintOperation *)printOperation =20
delegate:(id)delegate didRunSelector:(SEL)didRunSelector =20
contextInfo:(void *)contextInfo

Here the method:

     # Print our document
     def printShowingPrintPanel_(self, showPanels):
         printInfo =3D self.printInfo()
         printOp =3D =20
NSPrintOperation.printOperationWithView_printInfo_(self.rtfTextView,prin=20=

tInfo)
         printOp.setShowPanels_(showPanels)
         =20
self.runModalPrintOperation_delegate_didRunSelector_contextInfo_(
             printOp, self, "printOperationDidRun:success:contextInfo:", =
=20
None)

It gets this error:

  objc_sizeof_type: Unhandled type '=00'

I'm probably doing something stupid.
