This issue will be fixed in KDE4 by the great config cleanup.

Implementation hint: Conceptually keys SHOULD be bound to the actual hardware, and not
to one GUI representation. Both work, but it COULD confuse users, if we have multiple
GUI representations (e.g. "Dock Icon" and "Main Window").
If you think about this aspect more deeply, you will find out that this is the case already
today with "kmixapplet" and "kmix main application". It would really nice to rework this.
