Odd; your stack jumps off to QWizard and you don't show what value d is 
in frame 6. If I had to guess, I would say that d is uninitialized or 
was initialized but was subsequently free'd and not NULL'd off. Another 
possibility is that the QImage was constructed from raw data and that 
the raw image data is no longer valid.
