LinuxQuestions.org - Qt Warning when starting VirtualBox

This is the warning I get when starting VirtualBox

[root@jonas VirtualBox-2.1.4]$ pwd
/opt/VirtualBox-2.1.4
[root@jonas VirtualBox-2.1.4]# ./VirtualBox
Qt WARNING: Qt: Session management error: None of the authentication protocols specified are supported

I've installed VirtualBox with the rpm, but it does not start up.

Then I've installed VirtualBox from the .run-file. Still does not start up. I get the error above...

VirtualBox has always worked fine for me. Don't know what happened to my Fedora10-system. I did not change anything.

I really need to be able to continue with my virtual hosts for a work I'm writing at the moment !

UPDATE :

I've tried starting VirtualBox again as normal user :

[jonas@jonas VirtualBox-2.1.4]$ pwd
/opt/VirtualBox-2.1.4
[jonas@jonas VirtualBox-2.1.4]$ service vboxdrv restart
Stopping VirtualBox kernel module [FAILED]
(Cannot unload module vboxnetflt)
[jonas@jonas VirtualBox-2.1.4]$ su -c'service vboxdrv restart'
Password:
Stopping VirtualBox kernel module [ OK ]
Starting VirtualBox kernel module [ OK ]
[jonas@jonas VirtualBox-2.1.4]$ ./VirtualBox

Now I get a message from Bug Buddy saying :
