BUG/REG: fix float64index -> mixed float assignment
closes #7366

WTF? I pushed fb38fb6 and it says merged here: https://github.com/pydata/pandas/commit/3ea8c7ad6c0032d87aca5c82e0efba34d6cb9034 from the link on travis

https://travis-ci.org/pydata/pandas/jobs/26909698
 Well, the fix did the trick. I tested from your repo.
 glad it works for you! just a little confused why travis has a commit that doesn't exist on my end but somehow exists in the GitHub ether and travis is able to check it out and run it. somehow my test is there but not the fix :confused: 
 that weird Travis bug

it somehow picks up a different merged commit
 good ol' rehash to the rescue :sunglasses: 
 well for one thing this checkout line is wrong:

`git fetch origin +refs/pull/7367/merge` as there was only ever a single commit without a merge yet somehow one was created on GitHub
 shoudl be ok now ... it's checking out directly from the hash
 ok i'm going to get out of the car and get back in .... make a new pr because something is really screwy .. commit hash is there but the changes are not
