Package: scilab
Version: 6.1.0+dfsg1-3
Severity: important

Dear Maintainer,

When plottin scilab just opens an empty graphic window. Should be
reproducible with the simplest example:

x=[0:0.1:2*%pi];
plot(x,sin(x))

In the console these messages are shown (repeated multiple times)
whenever trying to plot:
