Comment 5 for bug 73509

Ok, the above scenario seems to be required, but not enough. One should also export the file in between 2 and 3, which causes the following logic in database/pofile.py to fail:

    def validExportCache(self):
        ...
        change_time = self.latestsubmission.datecreated
        return change_time < self.exporttime

(in case of qtwengophone/es, self.exporttime is '2006-11-24 19:18:05.808967', i.e. a day before self.latestsubmission.active_selections[x].date_reviewed)

Now I need to create a testcase in sampledata for this.
