I had a similar, perhaps related problem yesterday.  I had one dataset 
with GTK_PLOT_CONNECT_STRAIGHT, then added a second dataset with 
GTK_PLOT_CONNECT_SPLINE and the second plot went weirdo (technical term 
for FUBAR).

When I set both to SPLINE, I got;

ERROR:gtkplotdata.c:5274:spline_eval: assertion failed: (h > 0.0)


Yay.
