This bug has been fixed, but unfortunately I do not know which update fixed this. On Saturday (2009-08-22) I updated my 9.04 Ubuntu to all the latests updates and after the update the bug was fixed. Below is the list of packages my system was updated with. But like I said, unfortunately I do not know which package actually solved the problem. Good news is that it is fixed. :-) ======================== Upgraded the following packages: acpid (1.0.6-9ubuntu4) to 1.0.6-9ubuntu4.9.04.3 app-install-data (0.7.6) to 0.7.6.1
