[darcywong00]

Reported on Slack by @DavidLRowe

If I have a keyboard in a folder (inddv), then rename the folder (inddv test), then double-click on the inddv.kpj file, Developer 17.0.295-beta crashes.
same with 17.0.303-beta

Details for error report for Keyman app:
Application Identifier: tike-17.0.303-beta
