I see a very strange color effect in this version of Fcamera

"Stadard" Camera

Fcamera + ufraw to raw->jpg convertation

As you can see, there is a strange "vignetting". But it is not brightness, it is obviously color temperature.

Is it "known bug" or my personal headache?

P.S. I use maemo devel repos.
