xset fp rehash is not run after installing X fonts ?

[Shaul Karl <shaulk@israsrv.net.il>]

I have just installed xfonts-intl-european.deb.
According to xset man,

 fp rehash
	The rehash argument resets the font  path  to  its
	current  value,  causing  the server to reread the
	font databases in the current font path.  This  is
	generally  only  used  when  adding new fonts to a
	font directory (after running mkfontdir to  recre-
	ate the font database).

Yet neither xfonts-intl-european postinst nor update-fonts-alias
seems to do it.
Am I missing something or is it a bug ?
