yes - my computer crashes when accessing dangeling pointers ;-)
For the tech details: we should also monitor the general usage, since
for small count(), QMap is faster for accessing and it's always faster
at inserting (and often removing) elements

afaik the entire icon thing is shared among all processes, so dolphin
uses the same icons as plasma.

I just _assume_ that the opengl graphics system will make use of
glXCreatePixmap - at least for QPixmap::fromX11Pixmap()

In that case we /could/ run into the same issue of n GLPixmaps on 1
Pixmap - might be just overcautious, though.

Cheers,
Thomas
