Description okbug 2020-10-19 05:49:00 UTC 
SUMMARY


STEPS TO REPRODUCE
1. Set "Open new files in tabs" in Settings
2. Add a registry "Parameter" key in [HKEY_CLASSES_ROOT\AppXhptkdxysnj90q56w5z3sx7d7a55gse06\Shell\open] with value '--unique "%1"'

OBSERVED RESULT

Each new file gets opened in a new window (with a new process).
Passing the --unique argument show a dialog every time saying something like 'Another unique instance is running, this won't be the unique instance...' although there are no Okular processes running on the system.


EXPECTED RESULT

Open all (PDF) files in tabs of a single program instance.

This can also be reproduced by running okular --unique from the command line, without any registry edit.

Comment 4 Hannah von Reth 2021-07-07 11:14:36 UTC 
I don't think we ship dbus, so thats probably the cause.
Comment 5 Christoph Cullmann 2021-07-07 18:18:26 UTC 
Yes, there is no working dbus there.
Kate uses QtSingleApplication for that on Windows, but that is hacky, too.
I could try to improve the error message by checking better if some dbus session bus is around at all.

Having the same issue.
