Ok, I forgot to manually erase old tables installation, i.e. this
fixed my problem:

rm -rf /home/ondrej/repos/qsnake/local/lib/python2.6/site-packages/tables/

reinstall tables.

Sorry about that. This feature of Python is highly annoying, that it
picks up the old installation and things stop working.
