I can't get 0.7 to run with mysql. Simply upgrading a
tracker with
a mysql backend from 0.6.9 to 0.7 (including adding the
two lines to dbinit.py) resulted in an exception. The
HTML output is shown in the attached file.

I then tried a different strategie: Upgrading with
anydbm backend to 0.7 (works fine so far), then
exporting the tracker, changing the backend to mysql
and re-importing the tracker. This leads to the
following exception from roundup-admin import which is
similar to the other one.

mysql version is 4.0.18 standard
