Database Errors when closing BeerSmith 2.2.12

Every time I exit out of BeerSmith, I get error notices telling me the application failed to write to a database.  It turns out that these errors mean any ingredient add-ons I make during a session are not being saved.  I'm pasting in the latest error log, I appreciate any help/suggestions... this is getting increasingly frustrating & time consuming.

I am running Mac OS X 10.7.5.  Thanks!
