[launchd-dev] LaunchAgent suddenly appears in Dock bouncing when CGImageSourceCopyPropertiesAtIndex is called

I have tried adding to the LaunchAgent's bundle plist the key LSUIElement with a value of YES. This doesn't change the behaviour. The LaunchAgent continues to work properly and the dictionary obtained from calling CGImageSourceCopyPropertiesAtIndex is saved to disk which is what I wanted to happen.

Some more info. How do I stop the LaunchAgent appearing in the dock?

After calling CGImageSourceCopyPropertiesAtIndex the LaunchAgent has opened the profile: /System/Library/ColorSync/Profiles/sRGB Profile.icc
The LaunchAgent has also loaded the CoreGraphics framework which wasn't loaded prior to calling CGImageSourceCopyPropertiesAtIndex.

I'm thinking they might have something to do with why the LaunchAgent suddenly appears in the dock.

For further info I'm including my plist file for the LaunchAgent which lives in ~/Library/LaunchAgents/
