Disabling the fetchmsttfonts update

I learned about a new icon of the update applet yesterday, the blue one for optional updates. I wanted to say "I don't want this particular optional update, thank you". But how?
Short: to disable the fetchmsttfonts update, remove pullin-msttf-fonts.

YES # zypper rm pullin-msttf-fonts

Long:
I tried to add a lock on the patch, but it did not seem to have any effect.

NO  # zypper addlock --type=patch fetchmsttfonts     # or al -t patch

After looking in the raw update metadata (updateinfo.xml.gz), I found the solution: remove the package pullin-msttf-fonts, with the first mentioned command.
Curiously enough, also other guesses at adding locks do not work, in a different way:

OK  # zypper al fetchmsttfonts

This adds a lock for the new package that fetches the fonts. The lock actually does what I want, in a different way: it installs the patch but omits the new package. It is also the most obvious command.

NO  # zypper al pullin-msttf-fonts

This is different in that pullin-msttf-fonts is already installed. List-updates still lists the patch as needed but halts on a solver conflict when trying to install it. The locks seem to take effect only when committing the transaction, not when checking for the updates.

But still, I would like to have a clickety way for this. Am I spoiled?

KNotify Client

Korshak asked how to do emerge -uND --world && knotify "Done!". I thougt it would be a piece of cake, but apparently not.
The short answer, zypper in libnotify; notify-send Done, has a disadvantage of requiring a fair amount of GNOME software. But it does use a proposed freedesktop.org standard.
Then I find the method org.kde.KNotify.event, but its nice signature (ssavsayasx) means dbus-send (dbus-1-1.2.1-12) cannot invoke it (it cannot pass empty arrays, and it cannot wrap variants in arrays). No problem, let's use Python. But then we are blocked by knotify4 (kdebase4-runtime-4.0.4-19) reporting a wrong signature via the introspection interface.

# killall knotify4; cp /usr/bin/knotify4{,.bak}
# sed 's/type="a(ss)"/ type = "av"/g' /usr/bin/knotify4.bak > /usr/bin/knotify4

Now which event should we use so that the user actually sees the message? There are many of them, with user configurable actions. warning/kde seems to work out of the box.

#! /usr/bin/python
import sys
import dbus
m = sys.argv[1]
kn = dbus.SessionBus().get_object("org.kde.knotify", "/Notify")
i = kn.event("warning", "kde", [], m, [0,0,0,0], [], 0,
    dbus_interface="org.kde.KNotify")


That did it. But I still hope that there is a simple solution for KDE4 that I have missed.
