Lexical error on cyrilic label with space

[anton-z-s]

In Protege 5.0.0 and 5.1.0 (owlviz 5.0.3) when trying to display entity with label that contains both cyrillic letters and space symbol (like "пример примерыч") the error occurs. However, when trying cyrillic without spaces or english with spaces there is no error. This is strange to see in unicode.
Protege 4.3 with owlviz 4.1.2 handles such label perfectly.
