I'm seeing this as well all over the site. For example: I'll initiate a search in my browser which will take me to the results page. Then, if it update my query in the search box on the results page and hit enter, 90% of the time it just ignores my query and gives this error.
This makes the image search results page completely unusable for me and makes the search results page extremely frustrating to use.
