Hum, shame on me, forget that. To be sure of the response to give you, I
tried to reproduce it; and I found why I thought it was happening.
I have an item I want to appear both in background items and files ones,
and I have therefore written a thin wrapper that builds the item with
the right label, icon, etc. But I didn't thought Nautilus caches the
menu item *by its name*, and then my file item overwritten the
background one.
And since when bg menu is created/appears no files are selected, my bg
item was overwritten with the empty file one...

Perhaps the doc should make clear that the name is a unique identifier
for all Nautilus menus? But well, perhaps it's just me that is quite
stupid at this point.

So again, sorry for the noise, and thanks for the help!

Colomban
