[PATCH] [spice-gtk] DND: fix special case that file size is 0

[Cody Chan <int64ago@xxxxxxxxx>]

On windows guest, after dragging a zero-size file, the file will be occupied

by vdagent. For spice-gtk ignores this case, and stops sending data after sending 

a start message to agent, see here for more details:

http://lists.freedesktop.org/archives/spice-devel/2014-August/017184.html

I accept the suggestion of Christophe and fix the bug in spice-gtk.

Pay attention to the modification of 

​

agent_msg_queue_many,  I think it's a small trick.
