New weston-terminal crashes after resize

[Bill Spitzak]

The weston-terminal from git crashes on me pretty soon after doing a 
resize. It looks like the crash is when the mouse exits the window. I 
don't think this was true of previous versions.

It also appears that weston-terminals launched from *outside* of a 
wayland session (ie from the x terminal that I used to launch the 
x11-compositor) crash when the mouse exits. Once it does this it often 
crashes immediately when run the next time.
