layoutSubviews crash due to a division by zero in trackRect

[nferruzzi]

This is easy to reproduce, just set the same value for maximumValue and minimumValue.
I understand this may have not sense for the slider, still imho it would be cool to see a graceful degradation (maybe handlers could disappear?) and not a crash. Thank you

Thanks, I will check it out.
