How to clear the OCR queue when OCRWorker was not running?

NC 11.0.0 on Ubuntu 16.04
OCR 2.0.0

I tried to OCR a picture while OCRWorker was not running.

For that, now i have an infinite OCR queue on the top of the page.

Meanwhile, OCRWorker is running and OCR works but the reference does not want to disappear.

How can i remove it?

Uninstall and reinstall the app does not work.

I’ve filed a bug, hope it helps.

That quickfix helped me:
