copyright issues in kdebase/nsplugins

So, I'm crossposting this to kde-licensing and k-c-d, because it clearly 
belongs in the former, but I'm afraid nobody will see it there, just judging 
by its archives. If that's inappropriate, I'm sorry. :)

While trying to sort out some copyright issues in kaffeine-mozilla [0], it was 
noted that some of the same issues exist in kdebase/nsplugins. The summary:

If you can manage to read that annoyingly-wrapped output, it pretty much 
speaks for itself. So, yeah. I'm the messenger. Shoot me.

I only have the question: what can, should, and will be done about this? I'm 
hoping the copyright owners will be willing to relicense at least some of 
these files. I especially care about j[rn]i*.h, because some of those files 
are used in other projects besides KDE. Please keep me CCed, though, as I'm 
not subscribed to either of these lists.
