This error keeps coming back on your Ubuntu start-up?
No worries, you’re not alone. Fortunately there’s an easy fix.
Fire up the console (Ctrl+Alt+T or via the dashboard), and let’s get cleaning!
sudo rm /var/crash/*
Followed by your user password.
And you should be good. We’re simply deleting the logs the system generates upon an app crash, and so Ubuntu will not complain there has been an error anymore.
