Did the application crash after a login attempt? I'm getting segfault whenever I click "Grant Access".
On Kubuntu 18.04 (Kernel 5.5) using the Ubuntu PPA as well

What nextcloud server version do you use?
Does your nextcloud version authentificate against LDAP?
We have the same issues using an old nextcloud server version with LDAP authentification. We tested the newest version (without LDAP Auth) and the client does not crash.

Hi @etlam
We use 18.0.3 server.
No, we don't use LDAP.

When we try it with the nextcloud instant trial (https://try.nextcloud.com/, version 18.0.3) it works flawless with the client in version 2.6.4.
You can add a new account during the dialog is opend using the nextcloud tray bar icon and the link "Settings ..."
Therefore I hope that it is going to work well again after updating our nextcloud.

A fix for the "Grant Access" bug worked for me as described in here: https://github.com/nextcloud/desktop/issues/1878#issuecomment-609440316
- Open the login dialog
- Remove the account
- Recreate it

I have the same/similar issue on 2 machines now.
It works to install start and configure the client it also works to sync but apperently if you tr to sync some data it just crashes - no notice about that at all.
one time on lubuntu 19.10
other ubuntu 18.04
both machines are rather old and have not much memory..
i also just noticed that i think their tryng to sync the same folder so right now im syncing that folder to a newer laptop also running 18.04..

uh that shows me also a lot of
"too many open files" error in the sync client - but its still running and ram usage is 85mb and not growing..

Also getting segfaults. I've tried removing and readding the account, as well as reinstalling the client.
I've deleted a directory and tried resyncing it. It synced the full directory structure, but no files. When syncing, it shows syncing 0B of 9GB, as if it only finds empty files.
