@r0light Seems like a follow up error of the Snackbar move. Could you please look into this?
May also be a threading error

This should be fixed in the latest development version. Could you please check the build from http://builds.jabref.org/master/. Thanks! Please remember to make a backup of your library before trying-out this version.
