Description

The OpenCV 2.3.1 for Unix has a bug in icvCreateBackgroundData function , which could cause the error "Invalid background description file."
the end of data->filename[count] string is "\r\n" which would make the cvLoadImage(data->filename[count], 0) return null to IplImage *
change code in icvCreateBackgroundData function /OpenCV-2.3.1/modules/haartraining/cvhaartraining.cpp
if( len > 0 && imgfilename[len-1] == '\n' ) imgfilename[len-1] = 0, len--;
to
if( len > 0 && imgfilename[len-1] == '\n' ) {
imgfilename[len-1] = '\0', len--;
imgfilename[len-1] = '\0';
}
could make the opencv_haartraining do well
