Yes, and this was because I forgot to implement some necessary methods.
This is now fixed in the svn trunk. So if you can,please give it a try.

What the toggle_axisline does is simply to make the xaxis and yaxis
(which are responsible for drawing ticks, ticklabels, etc in the
mainline mpl) visible again, and make axis["bottom"] and etc
invisible.
One workaround is to make xaxis and yaxis visible but pnly to draw the
gridlines. Something like below.
ax.toggle_axisline(True)
ax.grid(True)
ax.gridlines.set_visible(False) # this is just to make the code not to
draw gridlines twice in future release of mpl.
ax.xaxis.set_visible(True)
ax.yaxis.set_visible(True)
for t in ax.xaxis.majorTicks + ax.yaxis.majorTicks:
t.gridOn = True
t.tick1On = False
t.tick2On = False
t.label1On = False
t.label2On = False
Let me know if this does not work, or there is a case that this cannot be used.
