I'm using Kubuntu 10.04, with a few GTK apps (Pidgin, Evolution), and want to set Chromium as my default browser. I've set the default browser in KDE's System Settings to chromium-browser, which works for KDE apps.
For GTK apps I set the same setting in Gnome Control Center, but instead of opening in my existing Chromium window, links from the apps open in a new window, with a error about not being able to access my profile.
How can I make GTK apps use open links in the existing window?
Edit: I should also add that when the new Chromium window opens, the following error is displayed twice
