Notebook error page after deleting data file #6475
Description
If I delete a data file using the notebook (Data... pop up menu -> file name -> delete file name link), the file is deleted, but the browser then goes to a blank page titled "Error | Sage Notebook". The browser is Safari 4 on OS X 10.5, in case that makes a difference.
William Stein reported on Sage-Support:
I've seen this. This definitely didn't used to happen. Somebody introduced this bug a few months ago. Please report it to trac. I'll fix it in September/October when I work on the notebook, if nobody beats me to it.
