packaged dotc script passes funny flags to jvm

-Xdock:name="" -Xdock:icon="/Users/dark/Downloads/t/dotty-0.2.0-RC1-bin-SNAPSHOT/icon-mac.png" -Dapple.laf.useScreenMenuBar=true

icon-mac.png doesn't exist. Having an empty name isn't a good idea, but why would we put dotty in OS X Dock in the first place?
