Hi Bryce,

I'll try to reproduce that event with today's daily build of Lubuntu
i386 desktop.

I didn't keep the picture, it was the default jpeg picture from the
webcam with my ugly face ;-)

I think the bug is still there, that the jpeg picture is not read by the
default picture viewer of Lubuntu, gpicview. But Xorg will not crash
every time I try this procedure (and I don't know what makes it crash).

Best regards
Nio
