I can confirm this. I now do have Thunderbird with Lightning 1.0b7 installed and working, but it still won't show in Default Applications. This seems like a regression from Natty where Evolution supported calendars (including Google Calendar) right out of the box, while Thunderbird needs a plugin manually installed by the user (two if you want Google Calendar support, as in my case).

I think this is not expected, since it is not so useful to open calendar data as standard text). In Oneiric Thunderbird is default email client. Currently Thunderbird7 beta is installed, and I noticed the Lightning extension for Calendar is not compatible with it yet. Will Thunderbird/Lightining be possible values for Calendar applications?
