oject selection text red...why?

i have a bunch of objects in my scene but only one when selected is red, im sure its a red flag of some sort but dont know. the same object when rendering moves out of place ruining my render, dont know whats wrong.
the red text that tells you the active object, at the bottom left by the axis thanks!!!

Upload blend file to http://www.pasteall.org/blend/ and tell us the download link

Got the same problem on 2 objects (the armature and another ordinary object) if not more, but I don’t think there’s any problems rendering for me. Though I would like to know what problem this red text is indicating if any. Here is a picture of the text:

Do you know what it indicates? Did a fast googling on it but couldn’t find anything related to it but this thread. I would rather not like uploading the .blend file here because its a big project for me that I have been working on for months and is soon done. Is it possible to help me with this little information or do you need more? :\
