I'm not certain, but my guess is the tiff file has an embedded color profile other than whatever your gimp is set to, and the conversion option is set to auto-convert without asking questions. Open Edit/Preferences/Color Management and check what "RGB profile" is set to and what "File Open behaviour" is set to.
