history() not working in python3 or python2

[priestc]

This is the same as if I used ipython as if I used ipython3

$ sudo pip3 install -U pybitcointools
$ ipython3
>>> from bitcoin import history
>>> history('1PZ3Ps9RvCmUW1s1rHE25FeR8vtKUrhEai')
---------------------------------------------------------------------------

    170             except:

    313     if s.startswith(u'\ufeff'):

During handling of the above exception, another exception occurred:

    172             txs.extend(jsonobj["txs"])
    173             if len(jsonobj["txs"]) < 50:

TypeError: Can't convert 'bytes' object to str implicitly

I'm actually trying to build a separate python package that does exactly what history() is doing (calling an external block explorer to get utxo) I want my library to return data that is compatible with how this library's history() function works. But it appears that history() is broken? I tried updating to the latest version but the error persists.

Oh, I came here to report something similar. This is not working for me and I tried Python 2 and Python 3:

h = bitcoin.history('192Tsb794VGi3VAJZ8zhHdjSRVFZpCywab')

I don't know if this is relevant, but this address has received Counterparty transactions.

I tried another address ('191vGngyDnpznFBNaWsKy5FySqwAWEhTBQ') and it worked for me.

@arhuaco in the maintime, you can use moneywagon.get_unspent_outputs() in place of history() until the PR gets merged.
