I keep getting the following fail with heroku + git...
$ heroku jammit:deploy --app XXXXXXXXXXX
===== Compiling assets...[OK]
===== Commiting assets...[OK]
===== Done...
===== Deploying assets for xxxxx-staging to heroku...
To git@heroku.com:XXXXXXXX.git
! [rejected] master -> master (non-fast-forward)
error: failed to push some refs to 'git@heroku.com:xxx-staging.git'
To prevent you from losing history, non-fast-forward updates were rejected
Merge the remote changes (e.g. 'git pull') before pushing again. See the
'Note about fast-forwards' section of 'git push --help' for details.
[FAIL]

$ git pull
Already up-to-date.
Any ideas what I'm doing wrong or should be doing differently to allow for pushing without having to force a push?
Thanks
