I've applied this additional logging to our production environment. I'll monitor it for a week and provide a feedback.

I had same error after migrating from OC to NC for a single user a month ago. As workaround I've removed 'share_folder' => '/Shared', from my config.php. Unfortuantly I'm not able to reproduce this situation now.

I think this is fixed https://github.com/nextcloud/server/pull/11862

But this still doesn't solve the issue. As a shared mount can thus be invalid and show up weird.

In my case the bug occurs in 14.0.3, steps to reproduce :

  • users A and B come from user_ldap
  • user A shares a folder with user B
  • delete A in LDAP, not in nextcloud
  • scan user B
centredecalcul picture centredecalcul on 29 Oct 2018

Fixed via #11862 on stable12, 13 and 14.
