Database error

Hi, Thanks for a handy plugin 🙂 It runs on our testing WP multisite, though quite slowly.

Looking at the PHP logs for the site in question, we are seeing a database error for every page query containing the bibtex shortcode:

“WordPress database error Incorrect integer value: ” for column ‘year’ at row 1 for query REPLACE xx_plugin_papercite(urlid, bibtexid, entrytype, year, data) <snip> – full error here: http://pastebin.com/mQkqdNE5

We are running PHP 55, WordPress 3.6 and Genesis 2 framework, and using a bibtex file on the server (the error also occurs when using CiteULike and Bibsonomy), and the database option enabled.

Any suggestions welcomed!
