Owncloud client 2.5.3 for OS X - code signature issue



I have just downloaded the latest version of the owncloud client for Mac OS X (2.5.3, build 11290), and when starting it get a critical issue in Little Snitch because there is apparently a problem with code signature of the application. Here is the Little Snitch full report:

action: deny
direction: outgoing
priority: extra high
process: /Applications/owncloud.app/Contents/MacOS/owncloud
owner: me
destination: any
port: any
protocol: any
notes: On 2019-02-19, owncloud tried to establish a connection to xxxxxxx. The request was denied automatically during Silent Mode because the code signature does not match what existing rules require.

This error never occurred with the previous version of the owncloud client.

Client configuration

Client version: 2.5.3, build 11290
Operating system: Mac OS X 10.14.3
OS language: English
