--- Comment #2 from pascalio <pascalio432 at gmail.com> ---
I'm sorry to say so but the bug doesn't seem to be fixed to me... In digikam
4.2.0 (from Ubuntu's repositories, Ubuntu 14.10) the USM still overexposes
images with radius < 1 and "amount" param sets the amount of overexposition...
Moreover, radius > 1 results in massive over-sharpening as compared to 3.5.0's
behaviour: I used to batch process some pictures in 3.5.0 with radius = 8,
amount = 1 and threshold = 0.05 to get a subtly sharpened image, but the very
same batch workflow in 4.2.0 yield a completely transformed image (ie. highly
oversharpened, much more global contrast, looks like an enormous radius blur on
top of an enormous USM contrast amount)

I compiled and installed 4.1.0 and the result was the same.
I get the same on to different machines running Ubuntu 14.10 and digikam 4.1.0
or 4.2.0.
Reproducible: still always
