Description Gabriel Masei 2018-10-15 14:59:21 UTC 
Steps to reproduce:
1. Open a Calc document in LibreOffice Online
2. Choose menu option Data->More Filters->Advanced Filter...

Behavior:
1. The dialog is not displayed
2. The document content part of the document window freezes. For example: the selected cell can't be changed.
3. The menu is still accessible but many functions doesn't work anymore.
4. After the document is closed it cannot be reopened. The UI freezes before the document reopens.
5. If the loolkit process that processes the document is killed or the LibreOffice Online is restarted then the document can be accessed again.

This was reproduced:
1. With the LibreOffice Online docker image based on master branch released on 11 or 12 october 2018: https://hub.docker.com/r/libreoffice/online/
2. With a local build on Ubuntu 18 of master branches from both Core and Online products with the latest commits on 15 october 2018.

This is troubling because once the issue is reproduced on a document the user can't access that document until the LibreOffice Online is restarted.

Btw, it's enough to kill the session in the admin console, or wait an hour when the session is killed automatically due to inactivity.

You're right but in order to do this we must be aware of issue occurrence. And this cannot happen unless the user informs us that the problem happened and on which document. From user's perspective this is very annoying and this is our most important concern and not how we can solve the problem once it occurred.

This is fine now.
