Hi, and thanks for your reply!

I'm sure you are aware of this but at least on my system the application isn't
really unprivileged:

  gb@big:~$ ls -al /opt/google/chrome/chrome-sandbox
  -rwsr-xr-x 1 root root 10692 2010-02-21 08:44 /opt/google/chrome/chrome-sandbox

I don't know why they think they need root and I definitely don't like
it... Part of a web browser running as root seems awfully close to Windows...
(I don't like google-chrome fiddling with my /etc/apt/sources.list but that's
another story...)

Please let me know if I can provide an other info or help in any way!

Sending this in private mail due to possible security aspects. Hope thats OK!

Sincerely /Georg
