Error: Parameter lists gives empty sweep

Hello,

I would like to know the reasoning behind this error in return of a monotonously incresing series of frequencies.

Examples:
a) 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 90, 100
b) range(5,1995/119,2000)
c) range(5,20,2000))

I have tried all the options above. Have I missed someting between 4.2a and 4.3, because the above behave as expected till 4.3?

Regards,
Onur
