Hello!
I seem to have a problem with the Count Pages plugin: When the plugin counts the pages (that's what it should do) of downloaded fanfic (epubs), it sometimes 'skips' random epubs?

What happens in detail: I use FanFicFare to download stories from different fanfic-sites. Then the FFF calls Count Pages to count the pages of he epubs just downloaded and it puts the counted number of pages as a number in a column. Some time ago I realized that some books have no values in the pages-column. I don't get a result shown, even though the plugin didn't report any errors. The epubs that are not counted vary by size and source. When I start the Count Pages plugin manually to count those without a page number (a handful, never more than ten-twelve at once) it does its job - although even then sometimes it 'skips' one ebook or the other.

edit: I just downloaded another handful of stories. Even though no error message showed, there were some ebooks that had no pages counted. I looked into the details of the Count Pages job and found this:
(It's the last book in this list)

Calibre and all pplug-ins are up to date. I don't know what is going wrong. Could you maybe help me? Thank you.
