      I'm not really sure of the importance of this.
      On one hand, it can cause virtually any Qt app to crash, OTOH hardly anybody will enter this keyboard combination.

      Hold <Left ALT> and press <NumPad9> four times when focus is in a QLineEdit.
      (I reproduced it in the fortune client example)

      ASSERT: "vk >0 && vk < 256" in file qwindowskeymapper.cpp, line 486

      Note: This keyboard combination can be useful if you need to enter some special Unicode characters you know the decimal codepoint for. For instance, typing ALT+"065" gives the character "A".
