Actually, since I didn't know what the thing is supposed to do, I checked the DrKonqi side of the code: The whole thing is never called, since DrKonqi never starts a service called "org.kde.drkonqi". There is a service foreseen called "org.kde.Krash", but it is not registered to the DBus.
So I think, I will drop those changes completely for now and fix this independently within DrKonqi and KDevelop in separate patches if you agree.

Sure, if there is no `a`, there is no connection. Thanks.
