Re: changing icon sizes no longer emits signal

[Kai Uwe Broulik]

(That's why confirmation prompts are pointless, one gets so used to just 
acknowledge them all that that I sent this mail mid-sentece :)

...so perhaps we should just change it to always emit the dbus signal 
manually when something changed, rather than it being nested inside 
exportToKDE4().

So, basically like David's patch, except maybe just with the explicit 
DBus call, so we can get rid of the emitChange call, which I think might 
be kdelibs4support material?
