Description: Ubuntu 8.04.2
Release: 8.04

Started within gnome session manager with

unclutter -display :0.0 -idle 5

the tool dies after a few seconds. When started from within a shell this happens.

eric@charon:~$ unclutter -display :0.0 -idle 5
unclutter: someone created a sub-window to my sub-window! giving up

What does it mean, is this a error that can be reproduced by someone?

Bye

This error happens if a second instance of unclutter is started and triggers the first time. The original process seems to become a zombie under some circumstances.

A test if an unclutter instance is already running on the current display would probably solve that issue.
