Hey,
I experienced a bug which resulted into SIGTRAP of weston (after a few
respawnings of weston-desktop-shell after SIGSEGV):

The bug appears when you run a client, then suspend it (^Z in my case) and then
hover with mouse or click on it or whatever.
Additionally, when you use right button, you can spin the window around its
axis (or move with i.e. smoke widget) (I'm new to wayland, so I'm not sure if
that's normal behavior)
I tried to track it in weston-desktop-shell and attached patch worked for me
(regarding the SIGSEGV)
Cheers,
mch
