This dictionary definition phrase with missing objects for the two verbs should only be parsable using the variant of the ERG intended for parsing dictionary definitions. I fixed a bug in the right-node-raising rule that was wrongly analyzing this example with the standard ERG, and will check in the change to `trunk' shortly. To compile the variant grammar, do ace -G erg-dict.dat -g ace/config-dict.tdl and you can confirm that the top-ranked parse of the above has the correct MRS.
