hm... too many calls to writeConfig are happening, and KConfigSkeleton is Too 
Dumb(tm) to know that nothing's actually changed. i'll take a look in a bit 
about this.

(i don't think it should be called at all on startup, actually)

right, we probably don't need the applet to also say the config has changed if 
(but only if!) we have a config loader, so something like this in 

if (!configLoader) {
    // manually call configChanged, otherwise let the loader do that for us

does that fix it for you properly?

another approach might be to just not forward the configChanged signal from 
KConfigSkeleton at all, but i'm concerned that will just open up other edge 
cases when a script actually does trigger a config change without using the 
config dialog or if/when KConfig gets change notification.
