OpenCPN on Raspberry PI2

[starnakel]

Recently i bought a Raspberry Pi 2, i've followed the following guide to install OpenCPN 4.0 on the RPI2: Pi Chart

The installation isn't the problem, the starting up is. After i launched opencpn it opens a split second and immediately closes, without giving an error.

The following log file is generated:
