How can this be solved elegantly?

It adds a ctor that takes a KPluginInfo::List& and adds the necessary branches to look within either the KService::List or the KPluginInfo::List.

There's one problem I don't know an elegant solution to, will point that out in the diff.


This, and the other patches from this set are also in kdelibs[sebas/pluginlocator]</pre>
