Assuming you have "Default" as your default raw profile, open a photo with no PP3 assigned.
Save the profile 1.pp3. Go to the other image via File Browser or F3/F4, go back to
this image. Save 2.pp3 and compare:

Same bug, different method:
Open a photo, make sure profile fill mode is pressed, apply Default ISO High.pp3, save
the PP3 to 1.pp3.
Change demosaicing method to anything else, save the PP3 to 2.pp3
Compare 1.pp3 to 2.pp3: http://bpaste.net/show/58705e0f6a5b
There should only be one difference: the demosaicing method. Instead, there are many
other differences.
2.pp3 correctly reflects the sliders and tools as you see them in RT, not 1.pp3.
