The second argument to execute() must be a sequence of parameter values.
You have one parameter value, the string b. To make a one-tuple, you
need a comma, as in "(b,)".

This traceback line worries me. I'm almost certain that you're not using
the latest version of the sqlite module. The module that is included
with Python2.5 is called sqlite3, and it lives
in .../python/site-packages/sqlite3/*
and .../python/lib-dynload/_sqlite3.so.
