Hi,

Running the attached program in Python 3.0 beta 2 gives the following error:

  File "C:\Python30\lib\json\decoder.py", line 21, in linecol
    lineno = doc.count('\n', 0, pos) + 1
TypeError: expected an object with the buffer interface

I can't figure out if there's an error in the program itself, but I
suspect this isn't working as expected.

Please let me know if there's anything I can do to help (if this is a
bug indeed).

Regards,
Swaroop
