> rpm -q k3b qt
That qt has been downloaded from kde-unstable (or testing, I don't
remember exactly) some time ago, so probably that's the problem...
should I upgrade?
OK, looks like you'll need qt-4.5.3 from testing
In the meantime, I'll add a minimal deps for both qt/kdelibs to k3b for
the next build, to avoid this problem.
