Please describe your issue in as much detail as possible:

When trying to launch the Steam launcher via the Desktop icon, no GUI shows up. No tray icon does appear. The application does seem to launch, as ps aux | grep steam returns a few lines.
Starting from the command line with steam produces the same output. The following lines keep repeating:

steamwebhelper.sh[1476042]: Using supervisor /home/<username>/.steam/root/ubuntu12_32/steam-runtime/amd64/usr/bin/steam-runtime-supervisor
steamwebhelper.sh[1476042]: Starting steamwebhelper under bootstrap steamrt steam runtime via: /home/<username>/.steam/debian-installation/steamrt64/steam-runtime-steamrt/_v2-entry-point

I would of course expect the Launcher to be visible and access my games. Right now, I cannot access Steam Settings (and opt in or out of the Beta program)

Steps for reproducing this issue:

1. Click on the steam desktop icon OR run steam in a terminal
2. Wait ... for a very long time.
