I had this problem for a bit. I found that changing the version repeatedly within the -app.xml worked for me. I mean change it from 1.0.1 to 3.9.9 or something else. Also I found that if I tried signing applications one after another the error occurred again so left it for a while came back 5 minutes later and it worked. Maybe it was my computer but I am all signed now.
