Error in Python console

[arvicco]

Running Beautify Ruby command always produces this error in ST2 Python console (ST2 Beta 2181, OSX 10.6.8):

Writing file /Users/vb/Library/Application Support/Sublime Text 2/Packages/BeautifyRuby/ruby/beautifier.rb with encoding UTF-8
 Exception in thread Thread-6:
 Traceback (most recent call last):
   File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/threading.py", line 522, in __bootstrap_inner
     self.run()
   File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/threading.py", line 477, in run
     self.__target(*self.__args, **self.__kwargs)
   File "./history.py", line 69, in run
 EOFError

Seems like there is some problem with child process that the command spawns (popen?). I have zero Python fu so no idea where to start fixing it...
