My Test Results
=============
This bug don't create problem in KDE (tested with Kubuntu 12.04 (32 + 64bit); Debian-live-7.0.0-i386-kde-desktop; Linux Mint 13 Maya-KDE-32bit) based distros. So, this bug isn't bug there.
I also tested with recent GNOME based distros (Ubuntu 12.04 (32 + 64bit), Debian 7.1.0-i386-GNOME, Kali Linux 1.0.3-i386-GNOME), problem exists.
But in pre-installed Dell Ubuntu 10.10 (Dell Ubuntu 10.10 Reinstallation Media.iso) this bug don't occur. After update to 11.04 this bug comes. Also in Ubuntu-10.04.4 this isn't bug.
