Wow - indeed, this does in fact happen after 5-6 tries. Seems like a race condition. Have you been able to make it happen with any other applications?
To clarify steps to reproduce:
1.) Run gedit with Alt+F2 'gksu gedit'
2.) Pin gedit to the launcher with 'Right Click > Keep in Launcher'
3.) Open gedit with the pinned launcher icon and then close it as fast as possible then unpin it
4.) Keep repeating 1-3 until you open gedit and no launcher icon appears.
At that point dragging the icon from the Dash when gedit is closed will not do anything (the icon won't appear)
Good spot! Thanks for raising this bug and helping to make Ubuntu better.
