Things like this often are caused by a corrupt PDF file. What types of edit operations are you performing?

One thing I would try is to do a "File>Save As" before performing any edits. Does this result in an error message? If so, and if there is a numeric error code on the error dialog, hold down the Ctrl key when you click on the "OK" button on the error dialog. What does the second popup say? If you don't get an error, try to edit this newly saved document. Does it also cause a problem on page 6?

What happens when you try to extract just page 6 and save it in a new file? Can you then edit this page in the new file?
