Yes, I was wrong about this property of QPL. On the other hand the combination of the following two requirements of QPL is enough to make the combined works impossible: You may distribute machine-executable forms [provided that you] ensure that all modifications included in the machine-executable forms are available under the terms of this license. When modifications to the Software are released under this license, a non-exclusive royalty-free right is granted to the initial developer of the Software to distribute your modification in future versions of the Software provided such versions remain available under these terms in addition to any other license(s) of the initial developer. Our discussion became too complicated and I am not sure on what we agree and on what we disagree. I will try to explain my current opinion in a separate message and if we have some disagreement we can continue from there.
