Comment # 2 on bug 1176023 from Benjamin Greiner

Nice! openSUSE bug report links to Debian bugreport which links to Archlinux
bugreport. Looks like an upstream issue (possibly fixed for 5.15)

python-3-qtwebengine-qt5 5.15.0 is not in Tumbleweed yet. Christophe has not
forwarded the update SR after our heated discussion. I forwarded now.

Ahmad, can you try with the updated package from
https://build.opensuse.org/package/binaries/KDE:Qt5/python-qtwebengine-qt5/openSUSE_Factory
?
I cannot reproduce the crash myself.
