Steps: 1. Launch Weston 2. Press and hold <Mod> and scroll the mouse wheel to zoom in. Release <Mod>. 3. Press and hold <Mod> and scroll the mouse wheel to zoom all the way back out. 4. While zooming out press the mouse right button. Observe Weston crash. I am able to reproduce this bug most of the times.

commit b2917a2fedd62a0938f0f34921fe57e5320d5fdb Author: Rafal Mielniczuk <rafal.mielniczuk2@gmail.com> Date: Sun Jan 5 20:04:59 2014 +0100 shell: run surface bindings only when focus surface is not NULL This fixes the crash when move, rotate or resize binding is activated while exposay effect is active. Steps to reproduce: - activate exposay - try to rotate the surface with mod + right mouse button - crash Closes: https://bugs.freedesktop.org/show_bug.cgi?id=72885
