Alt+F1 keyboard shortcut to Kickoff (application launcher) does not work

[brm]

This is a problem I have had for several months. IIRC, it first began while I was using Kubuntu natty, but has persisted through oneiric and is still there with the precise beta.

The problem is simply that the Alt-F1 keyboard combination does not work on this one x64 instance. It works with other machines running Kubuntu.

When I right click on the KickOff icon, it shows no keyboard shortcut. If I try to enter Alt-F1, an error dialog box pops up stating:

Conflict with Registered Global Shortcut - Plasma Desktop Shell

The shortcut 'Alt+F1' conflicts with the following key combination:
Shortcut 'Alt+F1' in Application Plasma Desktop Shell for action Activate Application Launcher Widget

And when I check |System Settings |Global Shortcuts |Plasma Desktop Shell, the shortcut does appear there. The config file entry appears to be:

.kde/share/config/kglobalshortcutsrc:activate widget 31=Alt+F1,Alt+F1,Activate Application Launcher Widget

So, I have two questions;
1) What is my best immediate work-around? Presumbably to overwrite the Global Shortcut, as the error dialog box invites me to do.
2) I see this as a bug, um, er, unexpected feature. Where would it be most useful to report it?: *buntu launchpad.net bug database? the KDE bug database?

Thanks in advance for any assistance.

Seems like some sort of corrupted config or something. Try resetting KDE to defaults if you don't mind losing your settings.
