Cyrillic addresses dont work with new version 0.8.1

[Ћирилица1]

I just install new version of roundcube:
Installing Roundcube 0.8.1 (Stable)

And find that Cyrillic addresses which work with early version, now not work!
Even written with punycode...

On some way, address was stripped:
Sorry, I couldn't find any host named xn----8sbncyg3cbfh.xn. (#5.1.2)

Regards!
