Yeah, Alpha is Anal ;-)

It works much better now, the pie chart demo looks great!

The bad news is that it still gets a SIGFPE, but in libart: 

GnomeUI-WARNING **: Could not open help topics file NULL

Program received signal SIGFPE, Arithmetic exception.
render_seg (p_forw=0x11fffec98, pn_forw=0x11fffec80,
pn_forw_max=0x11fffec84, 
    p_rev=0x11fffeca0, pn_rev=0x11fffec88, pn_rev_max=0x11fffec8c, 
    vpath=0x11fffed70, i0=3, i1=4, i2=5, join=ART_PATH_STROKE_JOIN_ROUND,

This happens when I create a new scatter plot, and try to configure the
X-data column. That is, Y-data is still set to None, but X-data just had
its value changed from None to eg. Column 1.

Seems like something is being plotted while the Y-data is stil
uninitilized. Maybe an apply button approach would be more suitable.

Cheers!
