It sounds like a issue with a plugin - have you tried deactivating the plugins you have installed and checking to see if the error still occurs?
You could also try opening an incognito window, you can do this by clicking on the spanner in the top right corner of the browser windows and choosing incognito from the menu. This kind of window disables plugins automatically. To quote from Google:
You've gone incognito. Pages you view in this window won't appear in
your browser history or search history, and they won't leave other
traces, like cookies, on your computer after you close all open
incognito windows. Any files you download or bookmarks you create will
be preserved, however.
Going incognito doesn't affect the behavior of other people, servers,
or software. Be wary of: Websites that collect or share information
about you Internet service providers or employers that track the pages
you visit Malicious software that tracks your keystrokes in exchange

you Learn more about incognito browsing. Because Google Chrome does
not control how extensions handle your personal data, all extensions
have been disabled for incognito windows. You can reenable them
individually in the extensions manager.
