PDE meshing (generateMesh) failing after solid operations

I'm trying to develop an algorithm to define, edit and solve finite elements problems using constructive solid geometry. The libs I'm using work well, but when it comes to generate the mesh, some complex geometries return the "Meshing failed for Hmax..." error whatever the Hmax, Hmin values are.
After some tests, It seems it is the very solid operation which makes the meshing fail, even if the operation is somehow "simplifying" the model, or if it leaves the model exactly the same way. An example:
Original model: Successful mesh generation
Modified (intersection with a cube to obtain a half): failed generation
How could I avoid this? For me, since the non-modified models are of the same complexity, it does not seem a "too complex geometry" problem.
Any workaround appreciated.
