Bug ID: 495573
Summary: Kscreenlocker_greet unable to unlock and segfaults
Classification: Plasma
Product: kscreenlocker
Version: git-stable-Plasma/6.2
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: gtp...@proton.me
Target Milestone: ---
SUMMARY
STEPS TO REPRODUCE
1. Leave the computer locked for a long time
2. Try to unlock it
OBSERVED RESULT
After typing the password, nothing happens. Clicking in the unlock button
doesn't start the validation, it's just stuck forever on the screen. Upon
further investigation, the logs showed it tried reading a nonexistant image; I
am not sure this is the root cause, as kscreen_locker itself changed to a valid
image after a while and was still unable to unlock

ADDITIONAL INFORMATION
This has been happening before this version, at least since KDE 6.1; I was
waiting to see if I could reproduce it before reporting (e.g I thought leaving
Android Studio/xwayland apps open were the root cause somehow, but this crash
has happened with everything closed and in standby)
