This error occurs since the last update of the play store you are trying to fix from google.
Apparently at the user level (I hope google engineers know something else) happens completely random and the same can be tlf generating it for days and disappear overnight.
One solution I can think of is to uninstall updates play store and try it. Note that then not take long to install updates again. Menu> settings> applications> All> Google Play store> uninstall updates> accept. Maybe just deleting the data and cache might work.
Now you'll have such a gone
