No mail for root.

I googled quite some more, and I still have no clue for this. Here's 
what I have so far :

# crontab -l
53 16 * * * export DISPLAY=":0.0" && /usr/bin/zenity --info --text "Test"

(yes, all on one line, the wrapping only comes from my mail client)

Still not working. Which leaves me clueless.
