Bug#515326: gdb trace

[Xavier Bestel]

Hi again,

I could ssh to my machine during a hang. there's nothing in the log,
nothing in dmesg. I could gdb the X server and client (carousel) but the
traces make no sense to me:

carousel:

(using xserver-xorg-video-radeon 1:6.11.0-1)

Anything I could try ?
