First of all, in Dolphin I made a partition visible and i clicked some .mov (videos) to watch them, it's Dragon Player the default player for mov! Then i clicked in a mov file but two times... I have now two windows of the same file... i decided to close one and then crash.. No more wallpaper (black background) no more taskbar few windows (Firefox..)... Before i stopped the connection then i couldn't use the bug reporter... I used ctrl+alt+backspace it produced nothing also i did ctrl+alt+F2 and reboot and reported this.
