What steps will reproduce the problem?
1. python pdb_print_ctypes.py WinXPSP2/Symbols/dll/ntdll.pdb

What is the expected output? What do you see instead?

Revisiting this issue using another machine, I'm able to now get viable output 
being generated. 

I suspect that the above errors were caused by a "mangled" installation by 
myself!

Glad things are working for you now -- I'll close the issue and we can reopen 
it if you run into the problem again.

I just moved to a Wheezy box and I'm experiencing the same issue. On Squeeze 
with Python 2.6 everything seems to be in order. My setup is the same as what 
Carl described above.

Hi Tamas,
  in my case, it was a mixed Python environment that was causing the issue - I was using an OSX machine and suspect/guess that OSX installed python packages and homebrew installed python packages were interfering with each other in some way(?).

Once I had ensured that homebrew python (and not OSX python) was being used, I 
then had to ensure that pdbparse, construct and pefile were being picked up 
correctly (I wimped out and did a pip uninstall followed by a reinstall). This 
resolved the issue for myself.

The other thing that might be worth watching out for is a pip install pdbparse 
followed by a svn based install - this might be also be causing some package 
based confusion if the above is not helpful in your case?

Hope that helps,

  Carl.
