I also tried the same sample scene on 2.74 and it seemed to do the same thing. i am sure it shouldn't be working like this.

It thinks that setting is wrong.
When scene was copied fully, the setting of particle system is copied.
Sphere object reproduced in new scene exists.
However, original Sphere object is set by the setting of reproduced particle system.
Because there is not original Sphere object in new scene, it is not drawn.

Think BKE_object_relink should call some BKE_particlesystem_relink on all its psys, but this does not seems to exist currently. Lukas, this is your area, will let you decide whether it’s worth spending some time adding relink func to particles, or if we consider that as known limitation/TODO for now.

sigh Starting investigating this, but particles are not my area, and it looks like their copying is rather primitive (e.g. psettings ID are never actually duplicated it seems when copying an object’s particle system, etc.). Addressing this is way out of scope of a bug, so will close this as TODO for now (added note ot our TODO list). Thanks for the report.
