Matthew,

I updated from svn, built, and installed, and I am having a similar 
problem.  A sample file is 
http://currents.soest.hawaii.edu/clivar/ladcp/I5S_2009/002.mat

Here is what happens:

In [16]:from scipy.io import loadmat

In [17]:a = loadmat('002.mat', struct_as_record=True, squeeze_me=True)

In [18]:a['p']['lon']
Out[18]:array(array(30.355230445182066), dtype=object)

n [20]:scipy.version.version
Out[20]:'0.8.0.dev6182'

I think this is the same problem that Ariel noted.  If I don't use 
squeeze_me but explicitly de-reference each of the two levels of arrays 
of shape (1,1), then I can get at the underlying variables.
