            Bug ID: 65986
          Assignee: wayland-bugs at lists.freedesktop.org
           Summary: Segfault from weston_compositor_pick_surface during a
                    destroy_resource
          Severity: critical
    Classification: Unclassified
                OS: All
          Reporter: ullysses.a.eoff at intel.com
          Hardware: Other
            Status: NEW
           Version: unspecified
         Component: weston
           Product: Wayland

Weston segfaults in a call to pixman_region32_contains_point() made from
weston_compositor_pick_surface() and originating from destroy_resource() (see
attached gdb backtrace).

This happens when selecting "close" from the weston client context menu and
moving the mouse after a split second of selecting the "close" option.  It is
somewhat tricky to reproduce due to the timing of the mouse move after clicking
"close".  I am able to reproduce with weston-terminal the easiest.
