Hello,

Months later, in some other issue, I learned about the feature of KDE
"slow keys" and what I have described is exactly the same behaviour and
I can now even reproduce this with just pressing and holding down the
Shift-key for around 8 secs; when it happens one must go to the KDE
Control Center and activate 'slow keys' (yes, they are not shown as
activated in this moment) and deactivate 'slow keys' again, and all is
fine.
