Bug 94069

When running a hello style application, it aborts in 1.9.92, while it works on 1.9.0 version of Weston.

To be able to reproduce (under weston):

  Configuration

[core]
modules=xwayland.so,cms-colord.so
shell=desktop-shell.so


  git clone https://github.com/hdante/hello_wayland
  cd hello_wayland
  make ; ./hello_wayland

  when cursor goes over the window, it aborts and displays the following message:
  listener function for opcode 5 of wl_pointer is NULL
  Aborted.

  A backtrace:

Program received signal SIGABRT, Aborted.

Running a nested weston over gnome-shell x11 user session, leads to:
  1.9.92 aborts
  1.9.0  works

Running weston from a VT
  1.9.92 aborts
  1.9.0  shows a broken cursor, pointer image does not display, but instead a black square box.


An example of what is expected can be found under GIT tree:
