User backend OC_User_IMAP already initialized

[tflidd]

Steps to reproduce

1. Use and update Nextcloud with IMAP external user backend.
2. Open News app or click on Nextcloud-logo on the top left corner
3. If I choose the files-app directly or any other app there seems to be no issue.

Expected behaviour

Nextcloud should be used without error.

Actual behaviour

Click on nextcloud-logo:

"reqId":"4NVm1YB1Z7+JYPQ7e8eb","remoteAddr":"ip","app":"core","message":"User backend OC_User_IMAP already initialized.","level":0,"time":"2017-01-17T22:06:31+00:00","method":"GET","url":"\/nextcloud\/index.php","user":"user","version":"11.0.1.2"}

News app (without any feeds):

{"reqId":"HE7cJlFy1KviaSsvuBXN","remoteAddr":"ip","app":"core","message":"User backend OC_User_IMAP already initialized.","level":0,"time":"2017-01-17T22:08:00+00:00","method":"GET","url":"\/nextcloud\/index.php\/apps\/news\/%7B%7B%20::Content.getFeed(item.feedId).faviconLink%20%7D%7D","user":"user","version":"11.0.1.2"}

nextcloud/news#84

It's doesn't matter if I use a local user or a IMAP user.

On NC 11.0.2 I still have the problem with some apps:

• news-app (@BernhardPosselt)
• weather (5 log entries) @nerzhul

other apps have no problem (Files, activity, gallery, mail, contacs, calendar, announcements, notes)

[ChristophWurst]

This is a debug log statement. Seeing this does not mean there's a problem:

server/lib/private/legacy/user.php

Line 148 in e3de4ed

\OCP\Util::writeLog('core', 'User backend ' . $class . ' already initialized.', ILogger::DEBUG);

.

I'm closing this therefore.
