Both. Qt licensing says only free for freeware.
And according to the FSF interpretation[1] of the Qt and GPL licenses,
distributing a linked binary would thus violate the GPL. The is not
really a problem with KDE, since the authors are unlikely to sue
themselves. One can even argue that they have implictly added an
exception to the GPL for linking with Qt.
However, XEmacs _is_ partly owned by the FSF. Distributing a Qt
version of XEmacs would almost force them to take action of some kind.
A legal battle (or even just threads) between the FSF and the XEmacs
developers would be a PR disaster for the whole free software
community.
