Ctrl + C interrupt event makes slideshow exit

[noraworld]

Sometimes Ctrl + C interrupt event makes slideshow exit after slideshow starts.

$ pokemon -ss
Starting slideshow with 768 Pokemons and a delay of 10.0 minutes.
Forked process to background with PID 10785.
You can stop it with 'pokemon -c'.

# Type Ctrl + C on prompt due to the misstype command
$ misstype ^C
Process Process-1:

This happens sometimes, not always. I have no idea when this happens.
