Launcher / Minecraft does only support SOCKS5 proxy

When launching the minecraft 13w17a launcher from command line using the following command.

java -Dhttp.proxyHost=[host] -Dhttp.proxyPort=3128 -Dhttps.proxyHost=[host] -Dhttps.proxyPort=3128 -jar /home/esabo/MinecraftDev.jar --proxyHost [host] --proxyPort 3128

Everything downloads correctly except launcher.pack.lzma. I was able to download this from a browser using the same proxy information (no authentication) with no issue, and able to get the launcher to appear and download all of the other files it attempts to download without issue, but cannot play because the "Version selector" drop down never populates.
