The faulty plug-in is caused by another component or website. Since the plug-in is installed when you install a toolbar from the same company, then you can perform a new installation of the toolbar or obtain a new version of the plug-in you are currently using. Usually a simple re-install fixes a lot of things including these errors. Also, you can append a simple function to the start-up line of Chrome to disable any dialogues that annoy you.
Right-click Google Chrome's shortcut and add --disable-hang-monitor after Chrome.exe.
