Is there a way to freeze the status screen to read the error message? Otherwise I have no idea if it's harmless or critical. According to smartcoin my GPU is merrily hashing away and shares are being accepted, but with that error message I'm not entirely confident that it's working.
If you time a ctrl+c just right, you can stop execution of the script and possibly see the error. (though, this will stop the script also, and you will either have to restart smartcoin again, or press 'o' to open it back up)
If the machine is local, you can use a desktop recording utility like gtkrecordmydesktop and play back in slow motion possibly.
What revision are you running?
Can you report back what you get if you run:
sqlite3 ~/.smartcoin/smartcoin.db ".schema profile"
I'm thinking that you don't have all of the schema updates....
