Fedora 10 got all enthusiastic with SELinux maybe? You might toggle SELinux in & out of permissive mode while you're in flipin'-switches mode. man setenforce & sestatus ymmv
I'm using Ekiga 3.0.2 and Fedora 10 with SELinux in Enforced mode. I have no issues.
In fact, I haven't had a single SELinux related issue since Fedora 9. I've been in enforced mode for almost a year now. If you do run into a problem there is a graphical tool that notifies you of SELinux denials and offers suggestions on workarounds. You can drop the SELinux jokes.
