Steps to reproduce

1. Well, I have no idea. The only think I understand is that it got something to do with zip and ODS (vnd.oasis.opendocument.text)? Or maybe I am wrong.

Expected behaviour

No zip related errors in the log.

Actual behaviour

A lot of zip related errors in the log.

I don't know how to do that, sorry.

We got the exact same error.

Did a bit of debugging:

• Where the error occurs

        public function extractFile($path, $dest) {
                $fp = $this->zip->getStream($path);
                file_put_contents($dest, $fp);
        }

• Seems to appear only while clicking in the menu on the left side (All files/Recent/Favorites/Shares).
• This is the first installation on the same server that causes this log entry.

[Niemand112233]

I have the same error while generating previews.

[szaimen]

Is this Issue still valid in NC21.0.2? If not, please close this issue. Thanks! :)

[eaggy]

yes, I got the same error with NC21.0.2 as well as with NC21.0.3

Same while generating previews NC 21.0.3.
