About the KWidgetsAddons license: I see that most files have "2 or later", but indeed
kmessagebox.cpp (at least) says "2 only". 

Changing that to "2 or 3", says kde-dev-scripts/relicensecheck.pl, would need permission
from 9 people:

- lgplv23: 
  blackie (   2 LOC): 085d737 
  mpartap (   5 LOC): ad90d3d 
    valir ( 175 LOC): 6717325,8ad3643,ed45f4b,de63ecb,98af1a1,42ad34c,395aeb3,28798e9,b3c57a2

  hadacek (  13 LOC): 4d2fb10,787f428 
     mutz (   5 LOC): e8fe529,5a595f0,a2ec044,7aab414 
ksvladimir (  27 LOC): 2edb719,c2a8111 
  phalynx (  20 LOC): 1988852 
   goutte (   2 LOC): 69a5299 

I have been playing that game with karchive for a while (chasing people and asking them
for permission), I'll do a few more, but I have a feeling it won't work out (e.g. already tried contacting N. Goutte).

Anyway.
I thought most of the time, icons were not actually licensed under the same license as the
code they're in, but the license of the theme they come from - e.g. oxygen is LGPL v3.
However in t he case of pinentry I have no idea - was the icon made by a KDE artist, or an external contributor?
