2.5.2 Client crashes after starting sync, kdewallet

[jtagcat]

Steps to reproduce

1. I logged in to the client with an app password (since I have U2F enabled)
2. Everything went well, except it said that I had not enough storage on the device (not true)
3. After pressing sync, it minimized to topicons redux for a moment and then crashed
4. After opening the appimage again (log starts here), I am presented with this:
   
5. After logging it, it goes to tray and crashes as before.

Terminal indicates problems with qt, from bitcoin/bitcoin#15677:
$ sudo dnf install qt5-qtwayland

Complete!

Running this from bitcoin issue removes the qt message:

Edit:
Version installed with dnf gets me logged in, but after opening the client again (rebooting) it logged me out.
This prerelease wanted me to create a kdewallet. Even tough the kdewallet app crashed first few times, after loading for a while, it managed to load up and I was able to create a wallet.
Since that, the prerelease worked fine. I installed the version from dnf again and that is aswell working fine. The version from nextcloud.com/install is also working fine.

2.5.3 Fixes this, tough the kdewallet seemed to be slow, inpatient users may experience problems.

Thanks for updating the issue. I will close it then.

2.5.3.url seems slow, I was playing around with 2.5.2 and kwallet, do not install kwallet, it broke gnome-keyring

Anything new about this problem?

[jtagcat]

Nope, nextcloud only works with kwallet, but kwallet brakes gnome-keyring until os reinstall (didn't find an another solution in months). Right now I use rclone via webdav.

It's mid-August and you still cannot use the AppImage on Gnome because of this issue. This makes the whole Nextcloud stack a pain in the rear to use and with no apparent fix in sight has left many searching for a new solution. Can we get an update on this?

@camilasan reopen the issue?
