Another movie to identify, if possible

[electroking]

Hello,

That recent thread about a Czech science fiction movie reminded me
of a film I have been trying to identify for years. I believe most of the
following facts are correct:

1 - It is a French movie.

2 - The action, or part of it, takes place in India.

3 - The musical theme is the slow movement from Schubert's
string quintet.

4 - One of the characters is a physician who explains at some
point that he is trained as a cardiologist but has to work as
a general practitioner as there are very few cases of heart
disease in his area.

I saw this movie (or a substantial part of it) on French language
Canadian TV maybe 20 years ago, and I never managed to identify
it. Any leads would be appreciated. Thanks in advance.
