129. Thunderbird 12.01 on debian

First build thunderbird
wget ftp://ftp.mozilla.org/pub/mozilla.org/thunderbird/releases/12.0.1/source/thunderbird-12.0.1.source.tar.bz2

Install dependencies
sudo apt-get install libdbus-glib-1-dev gir1.2-notify-0.7 libnotify-dev yasm checkinstall libzip-dev zip 

Remove the previous version and make sure that there's no existing comm-release directory
rm comm-release/ -rf
tar -xvf thunderbird-12.0.1.source.tar.bz2
cd comm-release/
./configure --disable-necko-wifi

The next step will take a little while (30-60 minutes on a slow computer)
make

And then install
sudo make install

Then install add-ons:
Lightning 1.4  (Sunbird is being discontinued)
Provider  for Google Calendar 0.9 (otherwise you won't be able to dismiss calendar reminders)
Engimail 1.4.1 (see http://verahill.blogspot.com.au/2012/05/encrypting-your-email-chat-and-phone-in.html)

14. Evolution email and Google Calendar(s)

The process is already described here:
http://www.ubuntugeek.com/how-to-sync-google-and-evolution-calendars-in-ubuntu.html.

It's not much of a post, but it may be of help to someone who tried the Google option when setting up the calendar sync in Evolution and found it less than satisfactory.

Edit 16/12/2011:
Recently (last two days, version 3.0.3-3) been getting error messages in evolution when trying to connect to my google calendar. While using the method described above for a while I switched to using 'google' instead of 'caldav' as the calendar type at some point. Well, it doesn't work anymore.

Here's how to use google calendar in Evolution:
New -> Calendar
Type -- CalDav


URL: caldav://www.google.com/calendar/dav/myemail%40gmail.com/events/
Use SSL: yes
User name: myemail@gmail.com
User email: myemail@gmail.com

Then clock 'Browse server for calendar and select the
+ /calendar/dav/myemail%40gmail.com/
         - myemail@gmail.com


Whether  you want to copy content offline or use it as default calendar is a personal choice.

Well, it's not working anymore. Same TLS handshake BS as before.

"Error loading calendar
Cannot open calendar: Unexpected HTTP status code 6 returned (Peer failed to perform TLS handshake)"

What I can't understand is why there is no good description of this problem on the web, given that Evolution is the default email and calendar client for gnome. I don't like thunderbird/icedove+sunbird/iceowl much, but things seem to work better in general there.
