With eviacam 2.1.2 (master branch) on Debian 9.1 (stable, XFCE) it is not possible to open the camera settings. (see screenshot) ![camera](https://user-images.githubusercontent.com/30769158/31315234-54cc6e08-ac14-11e7-999d-f09bcd148d97.png)

If I enable "Start eViacam at user logon" the error message > Impossible to get permissions for file '/usr/share/eviacam/eviacam.desktop' (error 2: No such file or directory) appears. (see attached Screenshot)...
