axis labeling currently broken?

Hello,

I tried the following code with the current CVS version of matplotlib.

    figure(figsize=(10,7),dpi=100)
    title(title_str)

    subplot(311)
    f=fill(list(t)+list(t[::-1]),list(etn1+dev1)+list((etn1-dev1)[::-1]),
     facecolor=(1.0,0.8,0.8),lw=0)
    plot(t,sig,"r")

    subplot(312)
    plot(t,sin(obs),"r")
    plot(t,cos(obs),"g")

    subplot(313)
    f=fill(list(t)+list(t[::-1]),list(etn2+dev2)+list((etn2-dev2)[::-1]),
     facecolor=(0.8,1.0,0.8),lw=0)
    plot(t,s2,"g")

    savefig("as1.png")

The result is displayed at

Unfortunately the labels to the left and at the bottom are weird.
Numbers in wrong places, sometimes overlapping.
Did I do something wrong or is this a problem with matplotlib?

All the best,
Jochen
