FileBot

When I launch filebot from console or with the launcher from Dashboard from deb package installation or with .sh script from portable bundle, nothing happens except in the sidebar the icon indicates that the proces has been launched (in console the process doesn't returned and has to be killed), no tray icon or window.
<code>filebot -script fn:sysinfo</code> returns

I'm running 4.0 on Ubuntu 13.10 amd64 on Linux 3.11.0-18.

Do you get any error messages if you launch the GUI from console?

Did the GUI somehow spawn outside of the visible screen area? You could try deleting ~/.filebot in case the configs are messed up somehow.

Can you reproduce the issue if you grab FileBot from the Ubuntu Software Center?
