Calendar (Google) not responding after a while and Evolution hangs

[cue]

When I start Evolution in the morning everything with the Google calendar thing works just fine.
After a few hours Evolution works fine but when I click on the Calendar button which would lead me to the
Calendar overview in which I have my default calendar referring to Google calendar Evolution gets grey and hangs.

Now closing and restarting Evolution does not help, kill the evolution main process does not help either.

As a workaround I could find out, that when I do a sudo kill -9 to the /usr/lib/evolution/e-calendar-factory after I have killed the evolution's main process and start evolution again everything works just fine.

I could see some similar bug issues here in launchpad already but decided to raise a new one as I think this current behavior is based on successors of the former bug fixes.

I hope this helps and thank you for your work.

I did not experience any further event of this bug on my system anymore.
So I assume it has been solved by some update which came in meanwhile.
Should I close this bug now?
