Moved .odt file to the desktop not visible if ooo thumbnailer installed meanwhile and thumbnail not generated yet

Binary package hint: nautilus

Please forgive me in advance for this very twisted bug.

Short form : when moving an .odt file (which thumbnail has not been generated yet, provided the "ooo thumbnailer" package is installed) to the desktop, it is indeed moved, but it is invisible on the Desktop.

How to reproduce :

1) let's consider you have file.odt in any directory
2) open this directory in nautilus : there will be of course no thumbnail
3) install "ooo thumbnailer" package
4) you can notice no thumbnail is generated either because the directory has already been "scanned" and the file was already there and didn't change
5) move it to the Desktop
6) expected behaviour : the file.odt appears on the Desktop and a preview is generated
** obtained behaviour : the file.odt doesn't appear although it was definitely moved **

after this step, to work around the situation :
7) open the Desktop folder in a nautilus window. Two possibilities :
7a) in some cases the loading of the Desktop folder will not complete and even other files will be missing (then you have to move the file back via the terminal)
7b) in other cases, it'll trigger something and the file will eventually appear on the desktop (with no preview)

you may also notice that, in order to get the right behaviour :
8) you may move beforehand the file.odt to any other directory (but not the Desktop) to force the creation of the thumbnail
9) then moving it to the Desktop will work as expect

Pfew :) I guess it's safer to uninstall ooo thumbnailer, but I guess that raises a Nautilus issue anyway !
Thanks for reading this !
