[Qt-upgrade] The app is crashing on linux with qt 5.15.8

[alexjba]

Description

The app is crashing on Linux when it's being compiled against qt 5.15.8. The crash seems to be related to nimqml or DOtherSide.

Note: We have colleagues that are using the debug builds with qt 5.15.8 or newer and it works. Could be a more specific issue that's reproducible on release, on specific flows or just on the nix builds.

Original crash

i was able to launch the build from https://ci.status.im/job/status-desktop/job/systems/job/linux/job/x86_64/job/package_nix/13/
i was not able to create account in this build, it fails with:

Please ask me, when you will need some help debugging.

So far there is a manual job:
https://ci.status.im/job/status-desktop/job/systems/job/linux/job/x86_64/job/package_nix/

Nix + Qt 5.15.8 branch:
#9232

Or you can run locally:

nix-shell --show-trace --pure --run 'make --debug tgz-linux V=1'

I do investigation on this issue in my PR too:
#9232

[yakimant]

Qt WebEngine was causing the problems, disabling helped: #13540

Now the question is - do we really need it? And if so - we need to debug the crash further.
