For every new file.  But slave.tex is not new, and it _does_ set
TeX-master locally anyway, so the default setting should not matter at
all.

There is definitely something wrong here.  Before such a thing
happens, what do you get upon entering

M-: TeX-master RET

_in_ the file where this problem occurs?  Does it display "master"?
If it does, does the C-c C-p C-p then indeed ask the master file
question nevertheless?
