that was indeed a good hint, I completely removed the
configuration entries for the softdevice, and suddenly
it started working. after analyzing the differences,
here is the culprit:
softdevice.AC3Mode = 0
softdevice.AlsaAC3Device = hw:0,1
softdevice.AlsaDevice = default
softdevice.avOffset = 0
softdevice.bufferMode = 0
softdevice.CropBottomLines = 2
softdevice.CropLeftCols = 2
softdevice.CropMode = 0
softdevice.CropModeToggleKey = 0
softdevice.CropRightCols = 2
softdevice.CropTopLines = 2
softdevice.Deinterlace Method = 0
softdevice.mainMenu = 1
softdevice.OSDalphablend = 1
softdevice.Picture mirroring = 0
softdevice.PixelAspect = 0
softdevice.PixelFormat = 2
~~~
softdevice.Postprocess Method = 0
softdevice.Postprocess Quality = 0
softdevice.Suspend = 0
softdevice.syncTimerMode = 2
softdevice.UseStretchBlit = 0
softdevice.vidBrightness = -1
softdevice.vidContrast = -1
softdevice.vidHue = -1
softdevice.vidSaturation = -1
softdevice.Xv-Aspect = 1
changing the PixelFormat to 0 or 1 makes it work with
correct colors, while 2 causes the segfault
