[wp-testers] Preview not always working

[Holly Doyne]

On 2.7 and have had few issues to this point.

Today, I tried previewing an unnamed post. It had autosaved, but I had not directly saved it nor added categories. 
Instead of getting a preview, a new tab opened up with a blank post. 

Repeated this with a couple of other attempts. Adding categories didn't make a difference.
Adding a name, then hitting preview worked after doing a manual save. 

No clue as to why this happened. Can anyone else reproduce this? 

Rates right up there with uploading media, it appearing in the post but the gallery window at the next upload saying Gallery (0)
