[Inkscape-user] How to get back to "normal" circles?

Hello,

for some drawing I drew a circle using the ellipse tool, and then used the node editor to give it a pie-shaped appearance. Now whenever I use the ellipse tool, I get the pie thingy, not the normal circle. Of course I could just delete the .inkscape directory altogether, but is there a better way?
