Bug ID: 474775
Summary: Endless copies of Kate spawned when opening files in a
directory containing a .git folder (aka fork bomb)
Classification: Applications
Product: kate
Version: 23.08.1
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: application
Assignee: kwrite-bugs-n...@kde.org

Needed folder structure to reproduce the bug (see next attachment for image)
I've found a bug in Kate that can be used to turn it into a fork bomb of sorts.
It's not particularly damaging since you can simply kill one of them to end the
loop, however it can get extremely annoying and possible cause loss of work if
you trigger it intentionally on a machine that's then left unattended for a
while.
STEPS TO REPRODUCE
1. Open Kate
2. Settings > Configure Kate... > Behaviour
3. Turn on "Open each document in its own window"
4. Click "Okay" and close Kate
5. Create a new folder named "kate_bug" and in that folder new folder "A"
6. Inside folder "A" create a "a.txt" file and a ".git" folder
7. Go back up and create a copy of folder "A", name it "B"
8. Go back into folder "A" and open the text file in Kate (double-click or via
open-with > Kate)
9. Switch to folder "B" and open the second text file using the same method
To aid with testing, I have also attached a zip file with the needed folder
structure.
OBSERVED RESULT
Kate opens normally the first time, however when opening the second file Kate
will continue to spawn new instances indefinitely until manual intervention.
EXPECTED RESULT
It shouldn't have done that.
