To reproduce, open emacs -nw -Q, then type a very long line, for example
typing around 100 random characters, then C-a C-k to kill the string
then maintain C-y to past many times to get a line taking 4 or 5 display
lines. This is your long line. Then hit C-j.

Repeat operation ten times or more to have many such long lines.

Monitor line number in mode-line while operating. At a point, it will
print L??

M-: (line-number-at-pos (point)) will return correct value so it is
likely to be a display problem.

Tested on Linux with emacs 23 cvs -nw in gnome-terminal.

Can't reproduce in X version.

This is not a bug.  From the Emacs manual:

     Line-number computation can also be slow if the lines in the buffer
  are too long.  For this reason, Emacs doesn't display line numbers if
  the average width, in characters, of lines near point is larger than
  the value of `line-number-display-limit-width'.  The default value is
  200 characters.
