I don't think that this is a good idea.
Doesn't this give a cyclic dependency ?
s5b.moc depends on s5b.cpp, and s5b.cpp depends on s5b.moc because it includes 
it ?

I'd suggest:

kde4_automoc( ${libiris_SRCS} )
qt4_wrap_cpp(libiris_SRCS s5b.cpp securestream.cpp )

This should just work. It will generate the moc stuff for the s5b.h and 
securestream.h header which can be included and should generate extra moc 
files for s5b.cpp and securestream.cpp, which will be compiled and linked as 
separate files.
And it should avoid the cyclic dependency.
