That was just a listenning, I try this 3 functio separately.

Ok. I try labplot on my i386 machine (debian testing) and the crashed didn't
happen. But on my powerbook (ppc, debian testing too), I can't plot any
functions. It also crashed one time when I try to export one picture with
imagemagick, which I could not reproduce. The plot of an data file works on
my powerbook well.
