Re: PyNIO TypeError?

Steve,

Thanks for the file. I was able to open it using Python 2.5 and PyNIO
installed from the file you listed below.

I then built Python 2.6 and numpy 1.2.1 and tried the same PyNIO. I
got the same error. (I think it was the same, but it was an error
nonetheless.)

I then built the latest PyNIO from source code using Python 2.6/numpy
1.2.1 and had the same problem.

I think there's probably an incompatibility issue, and hopefully
Dave will be able to look into this.

FYI for Dave and anybody else who is interested. I googled this error
and found the following:

   From the "what's new in python 2.6" page
   http://docs.python.org/dev/whatsnew/2.6.html

   object.__init__() previously accepted arbitrary arguments and keyword
   arguments, ignoring them. In Python 2.6, this is no longer allowed and
   will result in a TypeError. This will affect __init__() methods that
   end up calling the corresponding method on object (perhaps through
   using super()). See issue 1683368 for discussion.

You can go to the what's new page and click on "issue 1683368"
if you want further information.
