It seems I made a mistake before :(

I pushed a tag to my repository without pushing the corresponding commit. Therefore, the addon's version didn't get updated in the addon.xml file.

I've bumped the version and made sure the commit/tag are there this time.

*addon -
*version - 1.3.1
*url - git://
*tag - 1.3.1
*xbmc version - eden

Sorry for the hassle.
