It seems that this is an error code that is not defined by 
Python's errno module. We should provide a default 
Error class like "UnknownErrno136" in case we can't discover 
it from the errorcode module.  I have just commited something
along these lines.

The error should propagate because it indicates a real problem. 
Once we have a proper error and know which os-level operation 
actually failed we should be further.  Can you 'svn up', 
reinstall and report about the error/traceback again?
