Parser crashes on system's locked files (Windows)

[GoogleCodeExporter]

What steps will reproduce the problem?
1. pe = PE("C:\\Windows\\System32\\catroot2\\edb.log")

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

There should be no exceptions, but PEFormatError(), in fact:

Traceback (most recent call last):
  File "C:\Temp\pefile_mockup_3.py", line 15, in <module>
    pe = PE(file_name)
  File "build\bdist.win32\egg\pefile.py", line 1754, in __init__
  File "build\bdist.win32\egg\pefile.py", line 1810, in __parse__
UnboundLocalError: local variable 'fd' referenced before assignment

What version of the product are you using? On what operating system?

pefile-1.2.10-139.zip 

Please provide any additional information below.

File C:\Windows\System32\catroot2\edb.log is locked by this system process - 
svchost.exe running under NT AUTHORITY\NETWORK SERVICE account.
