Description

I wanted to get "all" the traces on my dev instance in the monitor so I changed the "minutes" query parameter to something like "99999".

When I submitted the page, I got an exception printed to the browser:

java.lang.IllegalArgumentException: Start key must be less than end key in range (start:1457aa24105 : [] 9223372036854775807 false, start:1452d6ac6a5%00; : [] 9223372036854775807 false)

We should be catching this before it happens so we can print a meaningful error message. My hunch is that submitting a "minutes" value that's greater than the "number of minutes stored" is throwing this error – if that's the case, it would be nice to have an excessively large value just return everything.
