KDE updates broke audio keys

[Hendrik Sattler <post@hendrik-sattler.de>]

Hi,

something steals my XF86Audio* events from kmix :-(
KMilo is _NOT_ installed (that piece of crap doesn't work anyway).

All the keys are defined as global shortcuts for kmix but retrying to 
configure it, tells me:
"Die Tastenkombination "XF86AudioMute" ist bereits der
globalen Aktion "Toggle mute" zugeordnet.
Möchten Sie die neue Zuordnung vornehmen?"

I'll translate:
"The shortcut combination "XF86AudioMute" is already assigned to the global 
action "Toggle mute".
Reassign?"

Well, telling it to reassign has, you guess it, no effect at all. This sucks.
Where is "Toggle mute" defined? I cannot find it anywhere.
