I compiled back, gui with debug=yes, I don't get a better stack trace.
If I compile also PRICE with debug=yes, I don't get a crash anymore!

I think the bug has to do with the backend, but gets triggered from 
PRICE? it doesn't happen on Mac or with the cairo backend.

line 258:
    if (shouldResize)
    {
        [currWin setContentSize:newWinSize];
    }

I can probably work around in PRICE that if there is no image, I don't 
send a resize, but isn't this a backend problem? I wonder.
