Can't use search panel like before, and about new tabs

Hi,
I've built GoldenDict from git (v078889d) under Ubuntu 10.04, and one thing I've noticed from latest changes is that I can't go up and down the list of suggestions (in search panel) with the arrow keys (keyboard). I'm only able to make one move in the list, and then the focus goes to the definitions or meanings area. In Windows I don't have such a problem.
The second issue, the new feature to double-click the tab bar in order to open new a tab doesn't work in my Ubuntu 10.04.
Regards,
