I have noticed this strange icon on my AndroidManifest.xml recently:

It looks like either a diagonal arrow or a box "leaking" something at the bottom right.
I must have gone through
a hundred times but I am not able to find it anywhere.
As I am using Subversive for Subversion integration I suspect it has something to do with it. Other plugins I use are m2e, FindBugs and EclipseMetrics. The IDE is an Eclipse Juno ADT
Does anyone have an idea what this icon means? I'm really curious
