This appears to be a bug in your code

  xmajorLocator   = MultipleLocator(0.3)
  xmajorFormatter = FormatStrFormatter('%d')

You are telling it to format the numbers as integers.  Try   

  xmajorFormatter = FormatStrFormatter('%1.2f')

This is a problem with matplotlib but I don't have a quick fix for
you.  I'll look into it more when I get some time.  For now, sharing
the same tick locator between multiple axes is not recommended, though
I understand this is a desirable thing to be able to do.  You can make
two identical locators, however, and shouldn't have troubles, which if
I understand you correctly, is what you observe.
