Bug ID: 434781
Summary: Dolphin doesn't release read lock on file
Product: dolphin
Version: 20.12.3
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: dolphin-bugs-n...@kde.org
Reporter: k...@trummer.xyz
CC: kfm-de...@kde.org
Target Milestone: ---
SUMMARY
This one is weird. Since updating to the latest TW snapshot with Plasma 5.21.3
and Frameworks 5.80.0, Dolphin seems to read-lock the *first* file being played
from an NFS mount by mpv.
STEPS TO REPRODUCE
1. mount NFS share
2. play a file with mpv
3. close mpv
OBSERVED RESULT
Read lock on the file by "file.so" persists. This means you can't delete the
file or the folder containing it.
Further files played with mpv lose their read lock some time after closing mpv.
EXPECTED RESULT
Read lock removed
SOFTWARE/OS VERSIONS
Operating System: openSUSE Tumbleweed 20210319

ADDITIONAL INFORMATION
- playing a file with VLC does not spawn a "file.so" thing.

"file.so" from Dolphin either when playing a file with mpv:
