6. You may develop application programs, reusable components and other
software items that link with the original or modified versions of the
Software under the following restrictions:
a. You make your items available in machine-readable source code
form free of charge to all users of those items. You may charge a
reasonable fee for the physical act of transferring a copy.
b. You explicitly permit users of your items to freely modify the
source code (possibly with restrictions on copyright notices,
attributions and legal responsibility), and freely redistribute
original or modified versions of the items.
c. As an alternative to (a) or (b), you may offer these application
programs, reusable components and other software items that link
with the original or modified versions of the Software under the
Artistic license or any GPL license.
Additionally, if you produce a patch, it must be;
b. The patch must be explicitly licensed by the following clauses
without additional restriction:
Permission is hereby granted, free of charge, to any person
obtaining a copy of this patch, to deal in the patch without
restriction, including without limitation the rights to use, copy,
modify, merge, publish, distribute, sublicense, and/or sell copies
of the patch, subject to the following conditions: Any copyright
notice and this permission notice must be included in all copies or
substantial portions of the patch.

3. Derived Works
The license must allow modifications and derived works, and must
allow them to be distributed under the same terms as the license
of the original software.
Now the QPL implies that 'application programs, reusable components and
other software items that link with the original or modified versions
of [Qt]' cannot be distributed under the QPL; but surely they are
'derived works'? Also, surely a patch constitutes part of a
'modification', and you can't QPL them, either.
I have no idea why Eric Raymond considers this not a violation of the
Open Source Definition.
