Description Ashish 2020-04-12 08:04:09 UTC 
SUMMARY
When Okular is already running and "open new files in a tab" is on in setting running okular --print-and-exit "some file" eventually kills the already existing instance of okular and printing dialogue is instanced two times.
First in the already existing window and then in a separate one.

STEPS TO REPRODUCE
1. Open okular. Make sure that "new files open in a tab" settings is checked. Also make sure that "Confirm on exit with multiple tabs" is off.
2. Open a file in okular.
3. Remaining in the same workspace (virtual desktop), Open a terminal and type okular --print-and-exit "some file"

OBSERVED RESULT
The printing dialogue opens twice. Once the file preview opens in the existing okular session and the other time it opens in a new window. After printing or cancelling in the first case the main window will all other tabs is killed.

EXPECTED RESULT
The printing dialogue opens just once and the preview is shown in a new window not interfering with the already existing instance.

SOFTWARE/OS VERSIONS

Don't attach to another instance if we're going to exit

It's rude to exit someone else we just attached to
