Problem with pdf ingestion?

[paxperscientiam]

This is not something critical for me personally, but I thought I'd share the issue I'm encountering.

sudo adsbibdesk -p /path/to/pdf/folder

This folder has about 800 pdfs. The script seems to be making progress until it suddenly spits out a fatal error.

Traceback (most recent call last):
File "/usr/local/bin/adsbibdesk", line 8, in
load_entry_point('adsbibdesk==3.2.0', 'console_scripts', 'adsbibdesk')()
File "/Library/Python/2.7/site-packages/adsbibdesk.py", line 180, in main
ingest_pdfs(options, args, prefs)
File "/Library/Python/2.7/site-packages/adsbibdesk.py", line 427, in ingest_pdfs
dois = grabber.search(pdf_path)
File "/Library/Python/2.7/site-packages/adsbibdesk.py", line 640, in search
data = open(json_path, 'r').read()
IOError: [Errno 2] No such file or directory: '/Users/cdr35/Desktop/The Cloud/Dropbox/paxperscientiam.com/files/library/library-main_collection/LIB-00136.json'

Not sure to make of this, though I wonder if I'm just using an outdated version of pdf2json (macports version).
