Google calendar sync always fails for me

[Michael Terry]

I don't know if this is a dup or not, I'm not knowledgeable enough in the problem space. Please dup as needed.

Every time I try to sync the calendar data on my Google account, it fails. I'm using a mako running ubuntu-touch/stable r15 (20150129).

Here's the latest bits from ~/.cache/upstart/sync-monitor.log when attempting a sync:

syn requested for account: "<email address hidden>" "calendar"
Pushed into queue with immediately sync? true Sync is running false

Anything else I should provide?

Here's the /home/phablet/.cache/syncevolution/google_+calendar_+20-2015-02-21-22-23/syncevolution-log.html file (edited to remove event names)

Looks like the relevant lines are:
