#1 bugs related to qt style

[Maksim Kirillov]

1. some black objects over the conference bar. They turn out to be a scroll buttons. In desktop, the scroll buttons also have some gap between them, but at least it's clear that they are scroll buttons.
2. group contents partially closes group title. I also saw the same effect in the event description, but could not save a screenshot.

I suppose both of the effects are caused by bugs in the default style. When I change the style with '-style' option, they are not reproduced. If I choose the "gtk" style, the application even have the familiar n900 look, and does not have the described bugs.
