This happens with basically any client:

• Open a client (e.g. weston-terminal)
• Maximize it with weston's keybinding (Meta + Shift + m)
• Fullscreen it with weston's keybinding (Meta + Shift + f)
• Maximize it with weston's keybinding (Meta + Shift + m)
• The client will be killed by weston

The interesting part is that (0,0) is being sent on the final configure. weston-terminal decides to go with its default size of 806x491. Because this doesn't fit the maximized resolution weston is expecting (but didn't tell it), it kills it with a protocol error.

You can get similar results doing fullscreen -> maximized -> maximized.
