Screenshot of warning that appears with every new document opened

With every new document I get a warning saying that this is an unsupported version of Collabora, and that this warning appears when there is more than 10 concurrent users or more than 20 connections. Yet when I go to the admin console, I see that I am the only user. Also this warning goes away when I change to a different browser tab and back.

What version are you using, please? (Help->About)
Comment 3 Johannes Rohr 2020-02-10 19:16:22 UTC 
(In reply to Andras Timar from comment #2)
> What version are you using, please? (Help->About)

Currently 6.2-3. I am always using the latest version from docker. https://hub.docker.com/r/collabora/code
Comment 4 Johannes Rohr 2020-02-10 19:19:22 UTC 
Just pulled the latest version, now it is 6.2-4

I also should say that restarting the docker container  (actually removing it and starting a new container) makes this error go away for a while but then it comes back.
Comment 5 Andras Timar 2020-02-10 20:24:10 UTC 
OK, thanks. I use the same docker version (with Nextcloud) and I cannot reproduce this behaviour. I'm setting the bug to NEW because I believe your screenshot.
Comment 6 Johannes Rohr 2020-03-06 14:48:34 UTC 
I just saw the error again, with the latest version, and I checked the administrator console, which correctly says that there is just one user connected and one document open.
Next I checked the logs for the docker container and I found that something is repeatedly crashing, although I have no idea whether it is somehow related:

Johannes, do you still get this warning with the most recent docker image? 

From the backtrace it seems generating one of the previews fails, it should be obvious which, because that file won't have a preview (unless there are more similar ones), perhaps you could try moving that elsewhere for the time being. The next question would be, why that file keeps crashing, but that's a question for another time.

I just saw it again. More logs?

Did you manage to find the file (or files) preview generation fails for?

I am not sure where in the logs you find that this is the cause of the crash. I also don't see any pointer to any particular file. So I have no idea how to start the search.
