Malformed query causes Assertion and shows backtrace

      1) Create a (ruby) client. I don't know of other clients that would allow a non-document object to be sent in a query.

      client = Mongo::Client.new(["localhost:27017"])

      2) Send a query with a non-document object:

      client['test'].find('user').to_a

      The server will print a long backtrace and raise an AssertionException

      Sending an invalid object to the server in a query causes Assertion and backtrace to print out.

      I realize the Ruby driver shouldn't be sending malformed documents to the server in queries but it seems like the server should handle this better.
