Hi, I have run into a segmentation fault while testing some demos from Qt 4.6.1, compiled with DirectFB support. I am using version 1.4.2, but 1.4.3 did not make a change either. Specifically, the problem appears in some accelerated rectangle fills, and more precisely when I move the pointer over the main menu of the Qt application. I am posting below the last portion of DirectFB debug output. Do you think this is a bug in DirectFB or QT?
