Comment(by humitos):

 Trying to reproduce this bug I found this traceback:
 {{{

 I not sure why I'm getting this error or how to reproduce it. It happens
 mainly at startup and not even over the same Journal entry the second
 time.

  * file: src/sugar3/graphics/palettewindow.py
    * CellRendererInvoker
      * Adding some log to the {{{__long_pressed_event_cb}}} I found it's
 called 7 times when you longpress over the icon and the third time it
 enters on the if ({{{self.point_in_cell_renderer}}} returns True)
    * CursorInvoker
      * Adding some log to the {{{__long_pressed_event_cb}}} I found it's
 called just once when you longpress over the icon
