I downloaded the source code of Apache2 and tried to compile and install Apache2 server (the reason I chose to compile from source code is that the RPM I got did not support httpd + svn integration)
After I restart my Suse Linux enterprise 11, What I saw was the following pop-up error messages:
(Popup Message 1:) The Panel has encountered a fatal error: The panel could not register with the bonobo-activation server (server code 3) and will exit. It may be automatically restarted.
(Popup message 2:) Nautilus can not be used now, due to an unexpected error
