After installing this new package I was able finally to get rid from incoming call screen glitch and I can keep my phone app in portrait mode. What I noticed is that when I receive call the status bar(containing battery, signal and other indicators) on top is missing. After I answer the call it appears. As far as I remember it was not so before.
It is not a big deal. I just wonder - is it only me or others with update hildon-desktop package experience same behavior?
