--- Comment #16 from Antonio Larrosa <larrosa at kde.org> ---
I'm using digikam 4.4.0 and noticed this problem too. For me (with over 2300
tags in my database) it took over 40 seconds to regenerate the tag tree view
(and my intention was to reorganize the tags, so it was quite unacceptable to
wait around 40 seconds each time I renamed or deleted a tag).

I looked into the source code and debugged digikam to find that every time I
stopped it, it was inside the icon loader, although most of my tags have the
same icon and in total, I think there are 3 or 4 different icons in use. So I
implemented an icon cache and now I can't even measure how long it takes since
it's instantaneous.

I'm attaching the patch below.
