KDE 3.1.3 Enter key weirdness

[Cameron Patrick <cameron@patrick.wattle.id.au>]

G'day all,

Have just upgraded to the latest KDE in Sid (from 3.1.2) and am noticing
some weird behaviour in Konsole[1] with the Enter key[2]: sometimes pressing
the Enter key will perform random window-manager-related actions, such
as changing to a different virtual desktop, moving windows around the
screen, focusing a different window, or lowering the Konsole window
behind other windows.  Has anyone else noticed this and/or have any idea
on what might be causing it?

Cameron.

[1] I've only noticed it in Konsole so far, but possibly other programs
are affected.

[2] Both the 'normal' enter key above shift and also the numeric keypad enter
key appear to have this effect.
