Retrieval error : TypeError: write() argument must be str, not bytes

[lucasgautheron]

I am using glacier-cli via git-annex. It is impossible to retrieve files because of the following error, which occurs with boto==2.48.0 and glacier-cli's head (e9f346d) using python 3 (I think that might be the issue...).

Here is the stacktrace :

$ git annex get raw_annotations/vtc/tsimane2017_C26_20170713.rttm --from archive-clear

Additional information: it works with python2.7 though
