SUMMARY
I can't set up a Google Groupware account through Merkuro Calendar. I run into bug 473897 where a newly-added account is shown in the list as "Configured account does not exist". However, unlike KOrganizer that allows me to manually refresh the list through a Reload button, Merkuro has no such button and I can't force it to refresh its account list. As a result, the account stays non-functional.

STEPS TO REPRODUCE
1. Go to "Settings" → "Configure Merkuro Calendar" → "Accounts", hit "Add Account"
2. Select "Google Groupware"
3. Hit "Setup"
4. Go to the browser window that appears, enter your Google account data, authenticate against Google, allow Akonadi to access your account
5. Go back to Merkuro. You now have an Akonadi window with the calendars and tasks from your Google account. Hit "OK"
6. The account list now shows your new Google account, but it says "Configured account does not exist". 

OBSERVED RESULT
The account list now shows your new Google account, but it says "Configured account does not exist". 
Probably Akonadi hasn't refreshed its account list yet, apparently it doesn't do that automatically. 

The workaround is to set up the account not in Merkuro, but in KOrganizer, where the account list has a "Reload" button that does a force-refresh. 

The underlying behaviour is bug 473897. However, in KOrganizer there is a workaround in the form of the Reload button. That way setting up Google accounts is awkward, but possible. In Merkuro it's impossible.

EXPECTED RESULT
The account list should show your new Google account and it should be populated and functional immediately.

This would probably require fixing bug 473987? If fixing the underlying bug is impossible, Merkuro should have a force-reload button like KOrganizer does.
