Since upgrading to version 2.0rc.2 I have been unable to sync new entries onto my laptop, although the main computer I use to store and sync files is working fine.

This is the report ID: 848478157

This is the error message from my laptop:

Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [mozIStorageStatement.execute]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: chrome://zotero/content/xpcom/db.js :: anonymous :: line 139" data: no] [QUERY: INSERT INTO tags (tagID, name, type, dateAdded, dateModified, clientDateModified, libraryID, key) VALUES (?, ?, ?, ?, ?, ?, ?, ?)] [ERROR: constraint failed]

Any suggestions gratefully received
