Sounds like a damaged document. ...
If you go to one of these "empty" pages and Select All, do you see numbers for height and width inthe control panel? Do they make sense? How about the x,y coordinates?
The coordinates actually seem to be in the minuses, although it will only let me check one page at a time before getting the spinning rainbow wheel and it then freezing.
And I bet the dimensions are probably using scientific notation, too. I've seen this at least twice in the recent past, and I don't know what causes it for sure, but I think it may be linked to converting a legacy .indd file to CS6. Once it happens, those pages are toast, I think.
If this was a leagcy file, I'll give you my standard "best practice" observation: Export the orignal file from the original application to either .inx or .idml and open that in the new version for conversion.
