Also observed this on the Weston 1.3.1 stable stack: wayland (1.3) heads/1.3-0-g84247b7 drm (master) libdrm-2.4.49-0-g7ddc98f mesa (10.0) heads/10.0-0-gb160fea libva (master) libva-1.2.1-0-g88ed1eb intel-driver (master) 1.2.1-0-g8f306e3 weston (1.3) 1.3.1-0-g5e3ff49 commit 312ea4ca42f87be5b03cbba4b48447bd9dc24097 Author: Ander Conselvan de Oliveira <ander.conselvan.de.oliveira@intel.com> Date: Fri Dec 20 21:07:01 2013 +0200 shell: Handle the desktop shell client destroy signal Set the internal pointer for the client to NULL. This fixes a segmentation fault at shutdown, where the shell would hang up before and cause libwayland to call wl_client_destroy(). When the shell was destroyed later, another call to wl_client_destroy() would cause the crash. https://bugs.freedesktop.org/show_bug.cgi?id=72550 Verified fixed on weston (master) heads/master-0-g917711b... ...will this be backported to 1.3? |
