I got the below error when saving a document.

I got the same error (or close to it) when trying to save an attachment to this page (which has a number of attachments, each of which has a number of versions).  I’ve hidden the name of the attachment (sorry – necessary obfuscation).  However, it was an excel spreadsheet where the name has spaces in it (if it matters)

Platform is JBoss latest being accessed through a mod_jk plug-in on Apache.

Any ideas?
