Added sniffer rule can't be removed

This is hrev46173.
After adding a sniffer rule to a file type, one cannot empty the text field to remove the rule again. An alert pops up informing us that the "Recognition rule is not valid: ^ Sniffer pattern error: unterminated rule". After that the text fied appears empty, but switching to another file type and back again, it's still there.
