Ok, so it's definitely a khotkeys problem, in KDE, & nothing to do with Qt.

I'll move this over to the kde-devel list, so they can see your test detail and evidence it's their issue, not Qt.

Thanks!

This issue started here

	Qt Keyboard Shortcuts broken in Qt 5.6 (since 4.8 at least). Reproducible test case included.
	http://lists.qt-project.org/pipermail/development/2016-April/025592.html

A Qt dev provided the detail that shows that it's a kde/kotkeys problem, not a Qt problem,

	"As you can see, Qt did receive "Shift+3" and "X", but the text lookup returned 
	the result for Ctrl+3 and Ctrl+X.

	As I said, the failure is in khotkeys: it needs to send the events in such a 
	way that the application can't tell the difference. Obviously, Qt 5 did."

Here's the testcase from the OP:

Note that the shortcuts fail only when used in Qt-based applications. They work fine in NON-Qt apps (GTK, JAVE, etc).

In addition to the info in original post, fyi I'm using
