Hi all,

When I use this plugin I'm getting some times following error:

calibre, version 2.60.0
ERROR: Unhandled exception: <b>TypeError</b>bject of type 'NoneType' has no len()

TypeError: object of type 'NoneType' has no len()

I run the plugin for some hundred files. It starts normally but when it reaches 100% is throwing out the above error without updating the pages column and I cannot figure out if it's because of a particular file and if so which file is causing it.

Any ideas?
