Looks like a Qt bug. Could you test with newer Qt, such as 5.12.3?
(In reply to Christoph Feck from comment #1) > Looks like a Qt bug. Could you test with newer Qt, such as 5.12.3? This crash happened just once. I can't reproduce with Qt 5.12.3 on Neon unstable edition or Qt 5.13 on Arch Linux.
reopen if you can reproduce
