see 387bdaa93fd6adb0cd8a930454e3be578fa5fdc0 in the kdelibs repo, how a
link will be opened depends on a few things now - the MIME type and what
method is used for opening the URL. if KRun is used the MIME type will
be detetermined and the prefered service for it will be launched, if
KToolInvocation is used first the preferred service for "text/html" will
be attempted with fallback to kde-open and xdg-open which solidifies the
behaviour of "mimetype-determination-in-calling-application" (see
kdelibs/kdecore/sycoca/kprotocolinfo.cpp)
