[Bug] Display backlight flickering in low light conditions

Display backlight starts flickering often in low light conditions. This does not seem to be connected to display timeout. Mostly it is somewhat fast and smooth, but at worst the intensity of the backlight may switch from the lowest to the highest and back without fade-in effect in between in a fraction of a second.

When the light sensor is covered by hand completely, the flickering does not happen.

Sailfish version is 1.1.0.39 Uitukka. I tested light sensor under good lighting conditions with csd and it reports 'Pass' with values 'covered: 0' and 'uncovered: 288'.
