font-lock doesn't refontify buffer

Binary package hint: xemacs21

If you open a source code file (C, php, etc.) with the font-lock enabled, the syntax highlighting works OK, except that the highlighting applies only to the current line. For instance, if you coment a block code in a C file, putting several lines between /* */, only the lines with the /* and the */ change color.

I get this behavior in both Ubuntu Dapper and Edgy.

The problem is solved by adding the following to ~/.xemacs/init.el:

(add-hook 'font-lock-mode-hook 'turn-on-lazy-lock)

Users of xemacs in other distributions said that this is not the expected behavior of xemacs.
