Black screen & division by zero

[George Tudosi]

Black screen on w7/64, immediately after loading a file:

MlRawViewer v1.4.3
(c) Andrew Baldwin & contributors 2013-2014
Using GLFW
Loading u'D:/temp\\M28-2358.MLV'
D:/temp\M28-2358.WAV D:/temp\M28-2358.WAV
None
Traceback (most recent call last):
  File "c:\Projects\MRV\build\mlrawviewer_win\out00-PYZ.pyz\GLComputeGLFW", line 315, in __draw
  File "c:\Projects\MRV\build\mlrawviewer_win\out00-PYZ.pyz\Viewer", line 374, in onDraw

  File "c:\Projects\MRV\build\mlrawviewer_win\out00-PYZ.pyz\Display", line 454, in prepareToRender
ZeroDivisionError: float division by zero

Traceback then repeated endlessly; log file grows very fast.

The problem has been fixed spontaneously after updating video drivers (nVidia K2000D). However, it should be nice if the software report a detected problem with a human-readable explanation.
