Crash with empty page

Issue reported by GStager at Bitbucket:

- Page #9
Page 0
Empty page!!
Exception while processing page 9:
Traceback (most recent call last):
  File "/home/stager/ocrodjvu-0.7.16/lib/cli/ocrodjvu.py", line 418, in page_thread
    result = self.process_page(page)
  File "/home/stager/ocrodjvu-0.7.16/lib/cli/ocrodjvu.py", line 401, in process_page
    page_size=size
ValueError: need more than 0 values to unpack

I think that empty page is a normal.

It certainly shouldn't crash on an empty page. Unfortunately, I can't reproduce it here. Which exactly version of Tesseract is that?

Can I get a DjVu that triggers the bug for you?

[jwilk]

Ping?
