As workaround you can remove the e2eeshare and then it works

@butonic @tomneedham @patrickjahns

Start by reviewing apps/user_ldap/lib/Proxy.php around lines 70-91 and apps/user_ldap/lib/User/Manager.php around line 84, then trace the reported failure when e2eeshare is installed and an EE trial is registered. Use the supplied stack trace and workaround as the reproduction context. Done means ownCloud continues working with e2eeshare installed instead of raising the IAvatarManager TypeError.
