Wrong internal validation rule

[naoliv]

Somewhere there is a wrong internal rule (I've disabled all my local rules to test) in JOSM:

2019-02-23 15:50:28.090 SEVERE: Skipping to the next rule, because of an error:
2019-02-23 15:50:28.092 SEVERE: org.openstreetmap.josm.gui.mappaint.mapcss.parsergen.ParseException: Encountered " "[" "[ "" at line 121, column 9.
