I was able to reproduce this on my dev site with a new LinkedIn application. This bug required some code changes to LinkedIn API endpoints and scopes we're requesting.
I've added you to a BetaTest user group on our site. If you'd like to grab an updated version of the LinkedIn provider plugin, use

.
There are two files changed in the build, so you can do a backup first.
/plugins/jfbconnect/provider_linkedin/provider/linkedin.php
/plugins/jfbconnect/provider_linkedin/profile/linkedin.php
