http authorization always fails
This may be the same issue as
#683 - it's hard to tell - but I've been unable to push to Bitbucket.org using HTTPS for at least a month (the same password works for the normal web UI). Using SSH works as expected so this hasn't been a major issue for me but it doesn't appear to be #939 as there isn't a proxy involved.
