Comment (by sysrqb):

 Replying to [comment:9 atagar]:
 > I'm not sure what you're trying to say. Exactly what code calling stem
 with what input is failing?

 It's completely possible I'm doing something wrong.

 {{{
 from stem.descriptor.networkstatus import BridgeNetworkStatusDocument
 ...
     with open(fn_ns, 'r') as fd_ns:
       ns_content = fd_ns.read()
     bridge_ns = BridgeNetworkStatusDocument(ns_content)
 }}}
 Where `fn_ns` is the filename of the networkstatus in the current
 directory. This yields:
 {{{
 Traceback (most recent call last):
   File "bridge_attributes.py", line 366, in <module>
     bridge_ns = BridgeNetworkStatusDocument(ns_content)
   File "/home/sysrqb/.virtualenvs/stem/lib/python2.7/site-
 packages/stem/descriptor/networkstatus.py", line 1466, in __init__
     raise ValueError("Bridge network status documents must start with a
 'published' line:\n%s" % stem.util.str_tools._to_unicode(raw_content))
 ValueError: Bridge network status documents must start with a 'published'
 line:
 @type bridge-network-status 1.0

 ...
 }}}

 (It actually prints the entire document, but I won't paste it)

 So what I was trying to say was that it looks like
 BridgeNetworkStatusDocument only reads the first line of the BytesIO
 object and fails to validate because the first lines does not start with
 'published '. Am I providing incorrect input?
