Yesterday when we reported on the new crawl errors we mentioned their was a language bug within the feature. The thing is, it is not specific to just Google Webmaster Tools. There are reports of the same issue on Google Analytics and Google News home page.
The seoconsult blog has a picture of the issue in Google Webmaster Tools:
Google's John Mueller replied that they are working on a fix yesterday and it should be fixed soon. He wrote in a Google Webmaster Help thread:
Thanks for the report, guys! We're aware of this issue and imagine it'll be fixed shortly.In the meantime, you can finally learn some webmasterly jargon in other languages :-).
But I am not sure if this is a larger bug than he anticipated.
