Debian 8: Nitrokey icon unreachable


I am using Debian 8.5 with gnome 3.14. for the Nitrokey Pro I have I installed the nitrokey app deb package.
The nitrokey icon is visible behind the applications menu.

How can I more this icon to a reachable place?

On Debian there are some problems with Qt lower than 5.4.2. Installing Qt from experimental branch apparently fixes the issue. Please read:
