--------------------+------------------------
 Whenever BridgeDB receives any type of descriptor file for which any error
 was raised raised by Stem while parsing that file, BridgeDB saves the file
 with the current timestamp and a suffix of `.unparseable`. Below you can
 see that BridgeDB has a whole bunch of these unparseable descriptor files
 from 16-18 May 2015. The thing is that the the line `transport obfs4
 173.246.106.214:2048

 ,iat-mode=0` shouldn't be triggering the error which Stem is raising,
 ''but the line below it should''. Well, it sort of should.

 It seems like the line below the one in the error is actually triggering
 the exception:

 From `stem.descriptor.extrainfo_descriptor.ExtraInfoDescriptor._parse()`:
 {{{

 There is also a potential second problem that the above IPv6 address
 ''is'' actually valid, and so we'll need to call
 `is_valid_ipv6_address([…], allow_brackets=True)`.
