Nextcloud client menu empty

Hi,
I am using Ubuntu 16.10 and Nextcloud client 2.2.4.
Since a few weeks the menu of the nextcloud client is empty after it is open for a while.

Anyone with an idea why this is happening or how i could analyze this?

Thank you,
Martin

You can enable logfiles, perhaps they provide more hints of what is going on:

Not sure exactly what how the upgrades are scheduled but version 2.3.0 should be released very soon (the owncloud version has already been released and Nextcloud already released some beta versions).
