Console/system log error: "Error calling sqlite3_step (1: cannot commit - no transaction is active)"

[biogon]

Been running my Hack Mini for a while -- it's based pretty closely off Tony's CustoMac Mini 2012 build (GA-Z77N-WIFI, 3570k i5, Seagate Barracuda 2Tb, 8Gb Corsair, 660Ti). Everything's great (except for the iMessage issue right now, but can't help that.)

 

In the Console and System log, I get this repeating error every 6 seconds or so. It looks like this:

 

Jan 8 21:40:00 tetraodontidae2 SystemUIServer[917]: DB Query: COMMIT TRANSACTION;
Jan 8 21:40:06 tetraodontidae2 SystemUIServer[917]: Unknown error calling sqlite3_step (11: database disk image is malformed) eu
Jan 8 21:40:06 tetraodontidae2 SystemUIServer[917]: DB Query: BEGIN EXCLUSIVE TRANSACTION;
Jan 8 21:40:06 tetraodontidae2 SystemUIServer[917]: Error calling sqlite3_step (1: cannot commit - no transaction is active)

 

(tetraodontidae2 is my machine name of course). I googled and searched here and found nothing at all relevant.

 

Booted in safe mode using the -x flag; tried booting off a USB drive and fixing permissions and doing a surface integrity scan in Disk Utility -- none of them fixed the problem.

 

Thoughts?

 

Thanks!
