Nextcloud linux client loops creating keyring

Greetings,

I am using simple desktop based on IceWM and Xorg. I was using it with Nextcloud client 2.5 and Fedora 25 and i was logged in cloud by password and it was using gnome-keyring to save it. That was fine.

Now I have installed Fedora 31 and Nextcloud client 2.6.1 (from repo). When I try to login via new login mechanism - I get infinite keyring creation dialog. That means when nextcloud client starts it asks for creation of new keyring named “Default” two times. I can either enter password or cancel it. When browser opens with authorizing link - client is logged in and window with keyring creation appears again. It will continue opening when i enter password or cancel it. It will not stop opening until client is running and is also blocking work in other windows.

I moved out .config/Nextcloud and .local/share/keyring folders and this do not change anything. Also I found that keyring is never actually created.

What I may do for further investigation?

Client output mention a problem:
Fontconfig warning: “/usr/share/fontconfig/conf.avail/05-reset-dirs-sample.conf”, line 6: unknown element “reset-dirs”
[87488:87488:1203/120429.160206:FATAL:memory_linux.cc(37)] Out of memory.

But I don’t see if that matters, because I have lot of free memory on PC and this happens only on client start.

Logdebug not show any significant errors, except

[OCC::AbstractNetworkJob::slotFinished QNetworkReply::ContentNotFoundError “Server replied “404 Not Found” to “POST https://cloud.xxx.ru/index.php/login/v2/poll”” QVariant(int, 404)
[OCC::WebFlowCredentials::stillValid QNetworkReply::ContentNotFoundError
[OCC::WebFlowCredentials::stillValid “Error transferring https://cloud.xxx.ru/index.php/login/v2/poll - server replied: Not Found”

I have installed 2.5.3 from older FC31 release and it works fine.

If this pops up directly after an update, you can directly contact the developers.
