in fact, Nautilus drag'n'drop uses text/uri-list but cut/paste uses 
x-special/gnome-copied-files. so drag'n'drop worked but not copy/paste.

OK, i've built something which works here, I found bugs in 
wxClipboard::GetData (it requests all the info with default direction 
wxDataObject::Get, whereas it should ask with wxDataObject::Set)

the gnome format is only accepted (i.e. only if direction is Set) and not 
returned, as we do not know what to put in the first line (which the command 
type: cut or copy)... maybe we could support it and always put copy?

if have got a problem also for wxClipboard::IsSupported(wxDF_FILENAME), 
wxDF_FILENAME points only toward g_fileAtom currently, so testing won't work 
if the clipboard content is x-special... should I put a hack???
