That particular use case is supported by not using a GdkSelection to store the
list of selected files in the first place. The only reason why you would use a
GdkSelection is, on X11, to use the X protocol as a form of IPC between two
separate instances of file-roller; since file-roller is a single-instance
application, there's no reason to use a GdkSelection to hold some URIs, since
there's no IPC taking place. 'Cut'/'Copy'/'Paste' operations should be
implemented inside the file-roller application singleton, by storing row
references to the GtkTreeView, or by storing a list of URIs.

Even if file-roller were to support multiple instances of the application, you
should use a better IPC mechanism, like DBus, instead of the X protocol, as it
has unknown latencies (which depend on things like your GPU stalling the event
queue) and a woefully inadequate type system.
