Never seen that, but I don't use G+ (don't think I even use Google Search, except from within Maps).
Have you tried rebooting the phone? Complete shutdown/battery pull? Uninstalling the most recent apps?

I uninstalled Chrome and installed Chrome Beta from Google Play store on my Galaxy Tab 7.0 Plus (GT-P6210) to resolve my problem as I too had the test service and cut, copy and paste problem and this seemed the work. Let me know if it works for you!
