Duplicate entry errors when viewing blocks page

I'm testing an upgrade from Pressflow 6.16 to 6.25 and receive this error with the jump module when viewing the blocks page. It does not occur on Pressflow 6.13. I've tried disabling the module and removing all entries for jump in the blocks table in the database, but no luck, they just come back after being re-enabled. Any help would be appreciated.
