Comment 25 for bug 52670

From an end-user POV, this definitely lands in the bug category (it just bit me today when I finally migrated my main email & RSS PC over to Edgy from XP - blog links in Thunderbird's RSS reader insisted on opening in Konqueror instead of in Firefox, even though I had already changed my browser preference. This bug report was the first hit on a Google search for 'thunderbird konqueror').

I like Yuriy's solution: point x-www-browser at 'kfmclient openURL <url>' as part of the default Kubuntu install. That should get the normal situation ('I don't care if it's a GTK or Qt app, I just want it to do what I want') right, and power users that want to use both Gnome & KDE and have them behave differently are still free to go in and change it.
