--- Comment #5 from Marcel Wiesweg <marcel wiesweg gmx de>  2009-02-22 21:26:43 ---
I set a breakpoint on read():

#0  0x00007ffff1977830 in read () from /lib64/libpthread.so.0
#1  0x00007fffea394400 in ?? () from /usr/lib64/libxcb.so.1
#2  0x00007fffea3948b8 in xcb_poll_for_event () from /usr/lib64/libxcb.so.1
#3  0x00007fffefcde8b5 in ?? () from /usr/lib64/libX11.so.6
#4  0x00007fffefcdeff6 in _XEventsQueued () from /usr/lib64/libX11.so.6
#5  0x00007fffefcb0634 in XCheckWindowEvent () from /usr/lib64/libX11.so.6
#6  0x00007fffde15196b in ?? () from
/usr/lib64/gstreamer-0.10/libgstximagesink.so
#7  0x00007fffed2a0764 in ?? () from /usr/lib64/libglib-2.0.so.0
#8  0x00007ffff1971070 in start_thread () from /lib64/libpthread.so.0
#9  0x00007ffff0f6a10d in clone () from /lib64/libc.so.6
#10 0x0000000000000000 in ?? ()

which seems to be from phonon/gstreamer.

A breakpoint on poll() is always caught by Qt's/glib's event loop. I believe
that is normal.
