If I configure a "downstream" project "B" in the Post build action "Build other
projects" for project "A", than in the project "B" a build trigger "Build after
other projects are built" appears for project "A".

If I save project "B", the build trigger disapears in project "B" and the post
build action disappears in project "A".

If I try to configure a build trigger "Build after other projects are built"
for project "A" in project "B", i can't save it.

It seams that Build trigger "Build after other projects are built" is not
saved / removed by job configuration.
