Filtering out the data I think is irrelevant, it looks like CoreData is being used for synchronizing bookmarks (rss feeds?) into sqllite, and has some internal error fetching. SIGBUS normally indicates a misaligned memory problem, but it looks like it is using an index as a pointer, or using an index against a null pointer (failure at 0x10).

Based on method names, I would guess this is an error accessing ~/Library/Mail/AvailableFeeds

I have seen a few issues with Mail when safari 4 betas are installed, the older webkit bundled with these has issues that are fixed with newer releases. However, your version string makes me think you are still using the shipping webkit.
