Nope, as I already replied here - problem is now resolved. The problem
was - I accidently set by root the login shell of my user to "zsh"
instead of "/bin/zsh". And according to very unclear note in manpage
of chsh - both current and new login shells should be described in
/etc/shells. I set a correct login shell for my user by root and now
the problem is resolved - chsh works correctly
