Hello Narcis,

yes they will:

	$ grep usr/share/applications /var/lib/dpkg/triggers/File 
	/usr/share/applications mime-support/noawait
	/usr/share/applications desktop-file-utils
	/usr/share/applications gnome-menus/noawait

	$ grep usr/share/mime/packages /var/lib/dpkg/triggers/File 
	/usr/share/mime/packages shared-mime-info

See /usr/share/doc/dpkg-dev/triggers.txt.gz for (a lot of) details.

The short answer is: "because transmission-gtk/postinst is generated by debhelper
fia dh_installmenu".

	$ cat /var/lib/dpkg/info/transmission-gtk.postinst
	#!/bin/sh
	set -e
	# Automatically added by dh_installmenu
	if [ "$1" = "configure" ] && [ -x "`which update-menus 2>/dev/null`" ]; then
		update-menus
	fi

I am not sure why this is still needed while there is already a dpkg trigger
doing the work.

Anyway, as noted elsewhere, the Debian menu system is being phased out.

Have a nice day,
