The magic number was changed several times due to the SET_LINENO
changes. At the end I changed it *back* to what we changed it to
after another change earlier during the 2.3 cycle. You may be the
only unlucky guy who missed both rounds of SET_LINENO changes.
Remove all your .pyc/.pyo files and be done with it.
