Have you ever seen this 404 error: 'www.mysite.com/Cached' in GWT?

[evolvingSEO]

Google webmaster tools just started showing some strange pages under "not found" crawl errors.

www.mysite.com/Cached

www.mysite.com/item-na...  <--- with the three dots, INSTEAD of www.mysite.com/item-name/

I have just 301'd them for now, but is this a sign of a technical issue?  The site is php/sql and I'm doing the URL rewrites/301s etc in .htaccess.

Thanks!

EDIT: Also, wanted to add, there is no 'linked to' page.

Are you using any type of framework or cms like wordpress or something similar?
