Streaming using Qt interface broken

I used to stream using the normal qt interface (ctrl-S), just by selecting a file to stream and pasting my own code like

:sout=#transcode{vcodec=h264,vb=800,scale=1,acodec=mpga,ab=128,channels=2,samplerate=44100,scodec=dvbs,soverlay}:http{mux=ts,dst=:8081/} :sout-keep :no-sout-ts-crypt-audio :sout-mux-caching=1000

or else depending on the case, at the end of the wizard in the field "Generated string output string" which replace all previous settings made just before using the UI. Doesn't work anymore with 2.1.0, nothing happens, not even an error notice.
