Error when find a concept by name

Hello! I have a problem when a try to find a concept by name in openmrs-core v.2.2.0-SNAPSHOT. The error message in the page is Error while attempting to find concepts - Invalid query And the jetty log is server.log

How to reproduce the issue i.e. which page to open? For some reason there’s no locale specified in the query.

I have opened Concept Dictionnary Maintenance page and type the word MALARIA
