Description of problem: open-browser.sh should use xdg-open instead of gnome-open. This would allow KDE users to set their preferences via KDE's System Settings. Version-Release number of selected component (if applicable): thunderbird-2.0.0.21-1.fc10.i386
he is right. gnome-open is depreceated even in GNome (since like forever ;-)).
Fixed in CVS. Please wait for next release.
