I have built a patch for this issue, roughly based on the patch that OpenSuSE submitted upstream at http://mail.directfb.org/pipermail/directfb-dev/2015-March/006879.html, but has so far been ignored by upstream.

I'll submit this update to updates-testing shortly.

directfb-1.4.11-3.el6 has been pushed to the Fedora EPEL 6 stable repository.  If problems still persist, please make note of it in this bug report.
