Bug Description

I am using Krfb as server for enabling remote access to this Ubuntu12.04 64bit machine.

The problem is that sometimes remote sessions changes the keybord layout completely on this remote machine.

The changes keeps persistent, also when all remote connections are closed and Krfb is quitted.

This is a violation of what Krfb should be allowed to do.


Steps to reproduce:

1. Enable krfb access over Menu -> Settings- > acces to workspace -> Security -> uninvited connections (setting a phassphrase there)

2.Use a scond computer and start the remote client programm krdc(I have used SLE Desktop 11 SP2 64bit with krdc4.3.5)

3. Connect (over LAN 198.127.1.x) to the Ubuntu 12.04 krfb server machine and give your phasprase.

4.Confirm the incomming connection on the Ubuntu12.04 krfb server machine

5.Operate from the client(SLED11SP2) on the server(Ubuntu12.04): Start virtualbox4.1.18(ppa of Felix Greyer)-> Start a Ubuntu12.10Quantal64bit vm on the server -> operate from remote client(SLED11SP2) in the vm(Ubuntu12.10):terminal,phasprases,synaptic,etc.)

6.After a while you will see that the keyborad layout works not normal(very cryptic, wrong key set, big changes to litte and invers).

7. This is not fully reproducible in time, so you will need to operate a while arround.

I have hit this on two operating attemts two times.

The problem might be security related, because the keyboard layout change is not introduced by the user at any time and happends just on running the remote connection.
