In the /english/search.lang.php the variable $l['find_all'] has a value of "Find all". The problem is in some environments the webserver will consider it malware because of that. It then deletes the file off the server. I suggest figuring out a different value we can assign. Perhaps "View all"?
Not really a bug (or rather a bug in the script which denies this phrase), but I agree that changing it would be helpful. I've already seen 4-5 support topics about it.
