[KPhotoAlbum] kphotoalbum git not compiling - geolocation plugin patch

[Tobias Leupold]

Hi Reimar!

Thanks for the patch! But apart from the fact that I can actually reproduce 
this crash: how can this even happen? How can a KIPI plugin crash KPA due to a 
category being there or not? Do the KIPI plugins even know about KPA's 
categories?

What does this Plugins::Interface::getTagTree() do? If it does not really 
affect anything, should we probably better use some dummy data?

I would really appreciate if somebody could clarify this to a KIPI-n00b ;-)

Cheers, Tobias
