python-dateutil will be updated to version 2.x and there may be changes that affect this package. If tryton will work with the newer python-dateutil, you can safely close this bug. If tryton really does require python-dateutil 1.5, please use Requires: python-dateutil15 for Fedora versions of the package until it can be updated.
This package only uses dateutil.relativedelta. It seems it will be fine with any version of dateutil.
