Binary package hint: unity
Occasionally when I click (sometimes accidentally) on the first item in the launcher, which I have as gnome-terminal (it may occur with other items in the launcher, but I haven't experienced it), it tries to move the icon. This would probably be okay if I were clicking and dragging it to try to move it, but I'm not, I'm just clicking on it (there may be some movement of the mouse that's causing it, but it's not deliberate). It detaches the icon from the launcher and leaves it hovering somewhere nearby. I can move my mouse around, but it doesn't move the icon. It is as if the icon is stuck. Clicking somewhere on the launcher again seems to fix it but clicking on the hovering icon does nothing.
It is not very reproducible because I cannot determine under which situations it occurs. I have not managed to deliberately cause it. I just now tried clicking randomly on the icon with various small mouse gestures (and also no movement) and it didn't happen. However, I did manage (twice) to do something similar. I managed to get all the icons to move down as if I were dragging all the icons down. They got stuck, even though I had let go of the mouse button and was moving the pointer around the screen freely. Again, clicking anywhere on the launcher but them back in place. It is as if the launcher is not correctly recognising ButtonRelease events.
I actually just now (in a second session of attempts) managed it but in my frantic clicking reset it before I could get a screenshot. : ( I suppose a screenshot wouldn't provide much information though.
This has happened with both my laptop's touchpad and my desktop's mouse (on those machines respectively, both fresh installs) so it is probably not to do with hardware.

I have just been able to reproduce this bug without any specific steps it just happens when you drag the top launcher diagonally to the upper left to upper right side and then leave it for a few time. After 15-minutes of testing I still dont have any steps, but it happens
