Debugging digikam

[Mario Frank]

Hi Martin,

I was extremely busy at work the last years and did not have any time for
digiKam. But I do have some implementation in my local branch which
is currently not merged. I could try to get this into digiKam.
I'll post to the bug today and describe my implementation and discuss
with the others in which version it should be integrated.

Cheers,
Mario
