Issues with running Xclient using xwayland.

[ashjas]

Hello,

I tried attaching the Xorg process to gdb to get a more detailed
backtrace.(by adding sleep to the child process)

here is the full backtrace from gdb:http://pastebin.com/pWE7px0S

as can be seen in the 3rd frame .. all seems to be fine as there are no
null values.
 xwl_screen->drm = wl_registry_bind(xwl_screen->registry, id,
                                           &wl_drm_interface, 1);

but when the xwl_screen->registry reaches to wl_registry_bind
(wl_registry=0x0, name=11, interface=0x7feb89670c60, version=1) here the
value becomes null. which propagates to function
wl_proxy_create (factory=0x0, interface=0x7feb89670c60)
where it segfaults at the line
struct wl_display *display = factory->display;

Any clues why?

Thanks

Regards,

Ashish
