zotero-better-bibtex: Error while exporting collection to Zotero-RDF

Hello,

I’ve got errors trying to export some of my collections to Zotero RDF files while BBT is enabled.

Debug log ID:

• YJMUWV36-euc
• 6VTRNZ3N-euc (second collection)
• G52R6DHP-euc (with cache disabled)

It seems that it only concerns elements with the connector’s timestamps (2013-07-11T07:00:00.000Z), as one of my collections without one is exported without error.

There are some errors given in the debug logs, which seem to imply it’s from Zotero or one of the files (?):

[JavaScript Error: "Component returned failure code: 0x80520001 (NS_ERROR_FILE_UNRECOGNIZED_PATH) [nsIFile.initWithPath]" {file: "chrome://zotero/content/xpcom/file.js" line: 47}]
