      My program does an FTP upload inside a QDialog. The user can cancel the dialog, which calls
      QNetworkReply->abort() and reject() of the dialog, after which the dialog is deleted.
      Still, the Qt mainloop tries to access somehow QFtpDTP::writeData() and crashes, as the accessed object
      was already deleted.
      See the attached valgrind logfile.
      I also attach the source to the dialog implementation, with which you should be able to reproduce the problem.
