On the docs-user-guide.f13.Accessing_the_Web.po file, at string 8 there is a small error.
"To start <application>Firefox</application> in KDE" should be
"To start <application>Konqueror</application> in KDE"
because string 2 explain that the default web browser in KDE is Konqueror not Firefox.
My apologies, I've understood why this was written like that.
Please forget this bug report.
