New description:
I have written a little application to demonstrate a Layout-Bug, caused by
the command SetFlags( B_PULSE_NEEDED)
write "jam" to compile the program and then start it, and you should be
able to see that the layout engine is not working.
If you go to the file: "NavigationView.h" and and uncomment SetFlags(
B_PULSE_NEEDED) it will work correctly again.
(it is called in the constructor of GroupView, and the layout is
contructed with the LayoutBuilder)

Comment:
There is no bug, you're using SetFlags() incorrectly. By calling
SetFlags(B_PULSE_NEEDED), you're stripping all other flags, including the
B_SUPPORTS_LAYOUT that gets set by the base class. What you actually want
is SetFlags(Flags() | B_PULSE_NEEDED).
