QDial notches are not paintet properly

QDial notches are not drawn properly if QDial is configured with large values. The attached image shows the problem:

The left dial is configured this way:
minimum: 0
maximum: 99
singleStep: 1
pageStep: 10
notchTarget: 3.7

The right dial is configured this way:
minimum: 0
maximum: 9999
singleStep: 100
pageStep: 1000
notchTarget: 3.7

Because the second dial values are simply scaled up by a factor of 100 the painting of the notches should be identical for both dials but it is not.
