Since you probably mean the KDE Free Qt Foundation I will chime in here.

Our agreements with Nokia and Digia guarantee that Qt is released under both 
LGPL v 2.1 and GPL v 3. This has the advantage (for us) that the patent 
clauses of GPL v 3 are explicitly confirmed by Nokia and now Digia.

The agreements require us to „license a substantial and material part […] of 
the KDE libraries“ (defined as kdelibs and successors) and of the „major KDE 
Software Packages“ (defined as kdeadmin, kdebase, kdegames, kdegraphics, 
kdenetwork, kdepim, kdeutils and successors)  „under an Open Source License“ 
(using the OSI definition).

Conclusion: From the perspective of the KDE Free Qt Foundation, I see no 
problems with using GPL v 3 for KDE applications.

We might run into problems, however, if we start a trend of making exceptions 
to our Licensing Policy. We would want to ensure that these exceptions are 
still using OSI-approved licenses, and that we do not run into software 
licensing conflicts.

I would therefore suggest to update our Licensing policy rather than allowing 
an exception.

Best regards, Olaf
