Hello,

I'm trying to use MythTV with qt/embedded and directfb using a DVB card.
i don't know if this is a supported setup, but at least my mythbackend
segfaults immediately when I try to start watching tv. I'm using debian
testing/unstable and my setup worked with the debian packages, but
trying to use qt/embbeded / directfb combination, this is 100%
reproducable, both with 0.14 and the current cvs. The backtrace below is
from cvs today.

If more information is needed, please feel free to ask,

juhis
