Hmm, yeah that would work too and it would solve similar issues in other
places. 

Although I already committed, it can be easily reverted and this change
applied.

Currently I see Q_DECLARE_METATYPE used in kdelibs for:

KTextEditor::Document*
KUrl
KUrl::List (in my local copy due to adding UrlList to KConfigXT)
KJob*

I guess the pointer cases don't really qualify, or how should that look
like? I wonder why they are declared as metatype at all.
