I have a branch in Launchpad that's set to automatically import translations to the branch. However, I noticed that there have been a lot of 'useless commits' lately where the translation files would be updated even though there were no changes to them.
For example, this revision:
fr.po:17 - "X-Launchpad-Export-Date: 2011-05-01 05:32+0000\n" + "X-Launchpad-Export-Date: 2011-05-02 05:32+0000\n"
Why are the translations getting updated when there are no actual changes?
