Scan fails on PDF file

The file at https://www.broadcom.com/collateral/pg/5756M-PG101-R.pdf fails to be scanned.
This is a bug in pdfminer. See euske/pdfminer#118

wget https://www.broadcom.com/collateral/pg/5756M-PG101-R.pdf
python -c "from pdfminer.pdfparser import PDFParser;p=PDFParser(open('5756M-PG101-R.pdf','rb'));from pdfminer.pdfdocument import PDFDocument;PDFDocument(p)" 
Traceback (most recent call last):

Note that on Linux using:

 wget https://www.broadcom.com/collateral/pg/5756M-PG101-R.pdf
 pdfseparate -f 1 -l 1 5756M-PG101-R.pdf  5756M-PG101-R-p1.pdf

creates a single page small PDF doc that has the same issue as the full doc

This is fixed alright.
