Using Manjaro / Arch linux, I wanted to install another browser. However, no matter whether I installed Opera or Chromium (via pacman) I always get an error when executing it (from both Application Launcher and shell).
Running Chromium it from the shell I get:
$ chromium

Similar error for Opera:

The by default installed Firefox however is working fine (so no network issues or such kind). I could imagine it is a configuration / safety issue (like Apparmor etc.).
Any ideas?
