Thanks for the logs. I'm marking this report as duplicate of bug
1036794.

To workaround this issue you can uninstall evolution-plugins, if you don't use evolution.
To completely remove evolution-plugins, open a terminal and run the command:
 $ sudo apt-get autoremove --purge evolution-plugins

Hope this helps.
