Preferences / Preferred Applications does not work properly

[Jaap A. Haitsma]

If I try to set my preferred web browser to a custom one (I want to set 
it to firebird)
I see that Preferred applications does not keep this setting. When I 
launch the Preferred apps app again both radio button of select web 
browser and custom web browser are disabled and in grey. Same thing 
happens when I try to select my custom mail reader.

When I change between the listed web browsers (in my case lynx and 
links)  preferred applications is saving this correctly but if I then 
for example launch the RHN website from rhn_applet it always use links 
even if I selected lynx

Anybody else seeing this? Or should I do something else to get this working
