Backtrace

Since the update to 4.12 (this is on Kubuntu 19.04 - disco) starting any app
results in a pop-up for wineboot having crashed.
This happens on two separate (but similar) systems.
If I close the pop-up the app then starts and seems to run OK.
If I don't close it the app starts up, but after a noticeable delay.

The backtrace.txt produce from "Save as..." in the pop-up window is attached.
