alacritty: crash when pasting (smithay_clipboard SIGPIPE)

Hi,

Thank you for Alacritty. When pasting my alacritty terminal often crashes. The trace is like below. Not sure if SIGPIPE is expected/should be ignored/etc. To reproduce more often try pasting 3 or 4 times in a row. Pls let me know if there is any more info I can provide or test etc.

thx, -m

Ubuntu 18.04 alacritty 0.9.0-dev (8f4b752) Wayland
