Compatibility problem with Google Calendar (XML mode) Rated 3 out of 5 stars

Due to previous alarm problem of Lightning, I finally give up CalDav mode and use XML mode of Google Calendar. It works fine is Thunderbird v22 version (and v15 version). But due to some other reason, I need to use Thunderbird v17.07 now, and download Lightning back to v1.9.1. Lightning then become malfunction. I wonder that no one report this problem. I also wonder if Lightning team just test local calendar and caldav calendar mode, but not other mode, before releasing the version. Hope Lightning team can solve it soon.

This review is for a previous version of the add-on (1.9.1).
