Those \t entries were a red herring.

kglobalaccel to multiple separate key combinations assigned to the same action
and type (default, custom).  Not sure if the UI supports such multiple
combinations, but the backend certainly does.

Anyway, more importantly, simply restarting kglobalaccel ('kquitapp5
kglobalaccel ; kglobalaccel5 &') fixes the meta key shortcuts, no need to edit
kglobalshortcutsrc.

So, it must be something in startup code of some kde/plasma component that
messes up "Meta" key.
But what and how?..
