Hi Nick,
just had a look, I assume you are using linux where signal 10 is USR1
(type kill -l 10 on your system).
DirectFB does not emit that signal. No idea where it might come from
otherwise..

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?
With regards,
