That will be a bug in vtysh, not bash.
This problem occurs with ssh also, after connecting to a RH9 box via ssh, I get the same quirks where the shell has to be reset. It appears that some signals get messed up, reseting the shell will also fix every time. Again with zsh I do not see the problem.
'Some signals get messed up'? It is a signal handling problem in the *application*, yes, in that it doesn't return the terminal to the mode it found it in.
