vout_Probe breaks everything

[Michael Flohr]

Hi,
just got vlc-0.2.83. 
The xvideo extension does not work anymore.
Lots of Gdk errors immediately after an attempt to open a window.
Strangely, using the new option --xvadaptor #num with #num any number
larger 0 helps, but then fullscreen does not anylonger work. I just
get a small image within a large black area, as I know I get it under
SDL.
I searched around a bit in the code, and found that simply disabeling
vout_Probe() in plugins/x11/vout_xvideo.c (I mean commenting out
most of it except the trivial last few lines) restores everything
to perfect working order for me.
By the way, the small program textxv.c, mentioned in an earlier post
works well for me.

Any suggestions what might be wrong with vout_Probe() ?
