Comment 1 for bug 385370

This is completely reproducible in current Ubuntu karmic:

 1. Run vinagre, connect to a remote host. maximise the window
 2. Ensure the mouse is within the vnc widget (ie events are being sent to the remote host)
 3. Close your laptop so it suspends
 4. Open your laptop
 5. Marvel at your inability to send useful events to things
 6. Drop to a console, killall vinagre, you can now send keyboard events
 7. lock display, unlock. all is now normal.
