It looks like you have attempted to run Geary before, since it reports your database is at version 21. You could try backing up ~/.local/share/geary, then deleting it, and running Geary again and seeing if that makes any difference.
Note however version 0.6 that you have installed is very old — the latest version is 0.12. If you add the official PPA to your system then Geary will be upgraded to 0.11, which may well work much better.
