So I moved upstream and asked about this on the LittleCMS mailing
list. From what the users and devs there were able to figure out,
there is no ICC profile embedded in my camera's JPG and TIF files. In
fact, DSLR cameras do not embed an ICC profile at all. The Digital
Camera File system (DCF) speci

Upon even further research you would find out that GIMP doesn't care
about that, because this is

I agree with you, it is definitely a bug. GIMP should not assume that
JPEG is in sRGB colour space whe

I just tested this with other Pentax cameras. So far, files from the
K-7, K20D and K-x all open in Gimp without asking me to specify color
profile, and they all incorrectly default to sRGB. All these images DO
have an Adobe RGB profile embedded. But those are the only cameras I
can check with that

Actually, you're entirely right. If I assign an Adobe RGB profile to
the picture, then save it, and re-open it, THEN it asks me what to do
with the color profi

I'm no expert about this so my wild-ass guess is that it doesn't ask
because there is nothing to do.
I've been pulling my hair out trying to figure out color management in Gimp.
In the preferences, I clearly have "File Open Behaviour" set to "Ask
what to do". My working profile is sRGB, and so is my Monitor profile.
I have "Display rendering intent" set to "Relative colorimetric". Yet,
