Basically this is a short form of this:

export KDE_SLAVE_DEBUG_WAIT=http
kdeinit4

Setting an environment variable to a certain value and then starting a program 
in that environment.

An "export" changes the environment for all calls afterwards, so sometimes it 
is better to just change it for one specific call by putting the variable and 
its value before the command.
(From the point of view of the program, in this case kdeinit4 this is 
equivalent)

Cheers,
Kevin
