Ubuntu 17.10 - Not working

[nimloth05]

If I try to launch the tool with linux I get the following stacktrace:

I don't know what the system tray should do for a simple program like this, so a possible "fix" would be just to remove this or only show it for windows. If desired I can look into this and provide a pull request (not supporting system tray on linux)
