BadShmSeg error with 0.2.80

[Michael Flohr]

Hi,

when using ./vlc --imdct imdct --downmix downmix to try to run
the new vlc version on my old 2.2.16 kernel of Linux, I get it 
running only with  --vout x11,
using  --vout xvideo  or  --vout sdl, which both worked fine
with 0.2.73, I get the following error:
Gdk-ERROR **: BadShmSeg (invalid shared segment parameter)
  serial 39 error_code 178 request_code 146 minor_code 2

Any idea, where this come from -- is it a bug?
