OwnCloud does not recognize .mwb MySQL Workbench file

Situation: I created a new “.mwb” file using MySQL Workbench inside of a synced folder.

Expected behaviour

Until a few weeks ago, the file was recognized and synced normally.

Actual behaviour

The file is not recognized at all. When it gets created, it gets labeled with the blue “syncing” symbol, but this disappears within 1-2s. Looking into the client, no activity is reported, neither a syncing process nor an error, nor an ignored file. I anyway checked the ignored files list and none of the entries suits the file.
Interestingly, if I change the files extension to “.txt”, it will still not be recognized or handled.

Steps to reproduce

  1. Open MySQL Workbench.
  2. Create new .mwb model file.
  3. Place file in OwnCloud directory.

Server configuration

Operating system: Debian
Web server: Apache
PHP version: 7.1
ownCloud version: latest version (stable channel)
Storage backend (external storage): shared host

Client configuration

Client version: latest
Operating system: Windows 10
OS language: german

Any help is deeply appreciated :slight_smile:

UPDATE: Rolling back the client to version 2.3.4 (build 8624) resolves the issue.
