Title:
  Icon of a launcher shown only on one desktop won't display

Status in Cairo-Dock : Core:
  Fix Released

Bug description:
  Hello,

  I have some application launcher that I display only on one desktop.

  If I am on the said desktop when cairo-dock starts, the icon is properly displayed.
  But if I am on another desktop when cairo-dock starts, then I change desktop, the icon is "invisible". The dock has an empty slot for the icon, I can start the software by clicking on the slot and the dock would be distorted when I pass over with the mouse, but there is just no icon.

  Note that if for instance I click right on the invisible icon, it
  proposes me as usual the contextual menu with inside the cairo-dock
  submenu, and the application submenu. This submenu displays the
  correct icon.

  Also if I go in the dock configuration ("Current items"), the item
  shows the correct icon as well. Only on the dock won't the icon be
  displayed.

  I am using the last bazaar repository version (revno 1206 from the
  09/09).

  I have a bunch of warning and messages when starting from terminal,
  but looks like this is relative to the current issue (I have a few
  other minor issue on cairo-dock, probably for later bug reports):

  Also I am ready to debug with anything which might help if I am given instructions.
  And I am even ready to patch the issue myself. I am just work-free again lately, so I get some time on my hands. Also I started looking the code, but some guidelines to where to look would be appreciated because that's the first time I look at cairo-dock's code. :-)

  Finally I read some pretty old forum discussions about graphics card driver issue. But it was said to be fixed. Also your "Recurrent Problems" page says it works with Intel cards now, >= 2:2.8.0, and I apparently have 2.19.0.
  So that's either another problem (hopefully), or a reappearing bug.
