I've run into this a couple of times when I'm searching for a question on the community. I type in my question and then often edit the text to see if rephrasing my question gets better results. It looks like something strange is happening where the page tries to update its location more than 100 times in 10 seconds and Safari blocks the page.
I'm sure I'm not typing 100 characters in 10 seconds so I'm guessing it's a problem with application logic.
