Git commit 3ff8c1f65ebeb5c0b7c2d2af59c9330558fcdb5e by Kai Uwe Broulik.
Committed on 27/07/2017 at 13:49.
Pushed by broulik into branch 'Plasma/5.10'.

[AppMenu Applet] Pass "ctx" as context instead of "this"

We copy "ctx" pointer by value into our lambda but by the time our timer fires, it might be gone already.
Instead, pass "ctx" as context to QTimer::singleShot so it won't fire when it's gone.
