gitflow fatal - could not read password... device not configured

[cwaudby]

I've just tried to push a hot fix in gitflow and got the following error:

Switched to branch 'master'
Switched to branch 'develop'
fatal: could not read Password for 'https://cwaudby@bitbucket.org': Device not configured
Could not push to develop from origin.

I can push commits OK manually... how can I fix this?

I have the same problem with my Bitbucket account.

Anybody can help us?
