color.c, colorcode

Locate:

                  /*
                   * Yes, this reset here is quite necessary to cancel out other things 
                   */
                  mudstrlcpy( dst, ANSI_RESET, dstlen );
                  if( ch )
                     mudstrlcat( dst, color_str( ch->desc->pagecolor, ch ), dstlen );

Change to:

                  /*
                   * Yes, this reset here is quite necessary to cancel out other things 
                   */
                  mudstrlcpy( dst, ANSI_RESET, dstlen );
                  if( ch && ch->desc )
                     mudstrlcat( dst, color_str( ch->desc->pagecolor, ch ), dstlen );

This particular part of the processing code does not verify that there is a valid descriptor before performing operations on it. Generally a bad idea. Most often affects switched imms, but could possibly be triggered by forcing linkdead players as well.
