I can no longer start Google Chrome on Fedora 14 (using GNOME).

I suspect that the issue is being caused by SELinux. How can I make it so that SELinux allows Google Chrome to start without issue?

# solution /use it with root/:
semanage fcontext -a  -s system_u  -t usr_t /opt/google/chrome/chrome-sandbox
restorecon -v /opt/google/chrome/chrome-sandbox

An autorelabel could help. You'll need to do the following:

As a user:

$ restorecon -R -v -F ~

And as root:

# touch /.autorelabel

then reboot
