Hi KDE developer,

Bug reported by the clang static analyzer.

Description: Called C++ object pointer is null
File: plasma-workspace/applets/appmenu/lib/appmenuapplet.cpp
Line: 167

```
153	void AppMenuApplet::trigger(QQuickItem *ctx, int idx)
154	{
155	    if (m_currentIndex == idx) {

Taking false branch	
?
156	        return;
157	    }
158	 
159	    QMenu *actionMenu = createMenu(idx);
160	    if (actionMenu) {

?
Assuming 'actionMenu' is non-null	
?

?
Taking true branch	
?
161	 
162	        if (ctx && ctx->window() && ctx->window()->mouseGrabberItem()) {
4
?
Assuming 'ctx' is null	
?
163	            // FIXME event forge thing enters press and hold move mode :/
164	            ctx->window()->mouseGrabberItem()->ungrabMouse();
165	        }
166	 
167	        const auto &geo = ctx->window()->screen()->availableVirtualGeometry();
5
?
Called C++ object pointer is null
```

So I simply add some checker for ctx, ctx->window() and ctx->window()->screen() pointers.

Regards,
Leslie Zhai
