Hmm, after a little more work it seems that the problem is actually with the 'clabel' command. To expand on Eric's example,
x = arange(5) y = arange(7) X, Y = meshgrid(x,y) z = X+Y c=contour(X, Y, z, [5]) clabel(c, inline=1) (causes exceptions in a fresh ipython session) clabel causes problems if only a single contour level is specified and returned. Maybe this is a bug?
