Pluto crashes when interrupting sleep

[yurivish]

I noticed that executing a sleep(200) command then interrupting a cell causes Pluto to crash instead of interrupting the cell:

I executed Pluto with using Pluto; Pluto.run(). Here's the error that comes up in the console:

julia> using Pluto; Pluto.run()

Press Ctrl+C in this terminal to stop Pluto
