Redrawing spectrogram may fail

[MJochim]

(Using Chromium 59)

I tried loading a large file (a 56 minute one of those FrauBovary thingies) and zooming in and out of it. I discovered that the spectrogram sometimes fails to render, leaving the respective signal canvas empty except for the text "rendering ...". In these cases, the following error appears on the console:

Uncaught TypeError: Cannot read property 'windowSizeInSecs' of null

I can recover from this error by simply zooming in or out - the spectrogram is then redrawn without a problem. I have not been able to find further hints about when this does or does not happen.

just tried this for about 10 mins and couldn't reproduce it. Might have been fixed by accident...
