If I search for "van eyck" (with the whitespace, but sans the quotes), I get an ugly error message. Searching for "eyck" actually solves my particular problem for the moment, but the error message is still ugly. Is it really such a crime to want to search for a string that includes the whitespace? Perhaps this could be explained somewhat more politely?

Also, if I search for "van\ eyck", the error message comes up and the input box contains "van\ eyck". Maybe there is a potential risk for a buffer overrun or something more exotic here? I think the input string should be quoted before being used in a regexp search.
