Cant start Nextcloud client on sway/wayland anymore.

[Achim Behrens]

Running unstable 21.04 with sway on wayland and since end of march i cant start the nextcloud client anymore.

First it looked like a qt/wayland issue and i installed qt5dxcb-plugin and qtwayland5. But it still doesnt start and just prints "Segmentation fault (core dumped)" now.

Status changed to 'Confirmed' because the bug affects multiple users.

I have the same bug, nextcloud-devs ppa is also concerned by the problem.
After manually installed debian unstable packages, nextcloud-desktop works.
I think there is maybe something wrong with compilation options.
