This bug has caused me a lot of troubles, lost nerves and data, incredibly
frustrating that this is ongoing for 3 years. I'm happy you were able to find a
workaround. Can you maybe give a further explanation? Are you supposed to close
Okular throughout? I tried copying into another directory using
{recovery_filename}, but the progress chart does not move. I'm not able to
create files inside that folder either. It keeps being stuck at 0Bytes and does
not change.
