I always thought it was as follows: you have your BSD KolourPaint. For the 
people who link against a free Qt edition, the code in itself becomes GPL, 
that is, any derivation they make under the _free_ Qt must be GPL 
(compatible?) as well. However, if they should happen to buy a commercial Qt 
edition, they can edit your KolourPaint code, link it with the nonfree Qt 
edition, and keep their modifications closed. But that's of course my 
interpretation of me as a non-lawyer, it's very possible that I'm very wrong 
about this (rather complex) issue.
