Bug ID: 391338
Summary: Dolphin crashes if a filesystem tree's permissions are
(massively) updated outside of Dolphin
Product: dolphin
Version: 17.12.1
Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: normal
Priority: NOR
Component: general
Assignee: dolphin-bugs-n...@kde.org
Reporter: bugh...@gluino.name
CC: elvis.angelac...@kde.org
Target Milestone: ---
Application: dolphin (17.12.1)
Qt Version: 5.9.4
Frameworks Version: 5.43.0
Operating System: Linux 4.15.3-300.fc27.x86_64 x86_64
Distribution: "Fedora release 27 (Twenty Seven)"
-- Information about the crash:
Dolphin was (probably) open on a filesystem tree that I was updating by script,
changing the ownership, permissions and SELinux attributes. While a whole lot
of permissions geot updated, Dolphin crashed (this happened twice). Is it
overwhelmed by too many messages?
The crash can be reproduced sometimes.
-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
