I had the same problem and I solved it in the following way:
Paint on an intermediate surface
- 1. the fill with fill_preserve and with the desired alpha
- 2. the stroke with stroke_preserve and with the clear operator
(this removes the fill in those regions where the stroke is going
- 3. the stroke with the desired alpha
Hope that helps,
