color.c, colorcode

Locate:

            case 'D':  /* Reset to custom color for whatever is being displayed */
               strncpy( code, ANSI_RESET, 20 ); /* Yes, this reset here is quite necessary to cancel out other things */
               if( ch )
                  strncat( code, color_str( ch->desc->pagecolor, ch ), 20 );
               break;

Change to:

            case 'D':  /* Reset to custom color for whatever is being displayed */
               strncpy( code, ANSI_RESET, 20 ); /* Yes, this reset here is quite necessary to cancel out other things */
               if( ch && ch->desc )
                  strncat( code, color_str( ch->desc->pagecolor, ch ), 20 );
               break;

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.
