If anyone can run this in valgrind and reproduce that'd be really useful.

All reporters so far use Qt 5.9.0.

I can easily crash plasma with scrolling over sound/volume systray icon. Although it does not crash every time.

I have never used valgrind and have no spare time atm to read docs, but if there is some easy copy/paste valgrind command I would more than happy to run it :)

This is probably unrelated to plasma-pa, see also bug 381525.

This is indeed a regression in Qt 5.9.
