Bug ID: 467639
Summary: Crash after closing a deleted file
Classification: Applications
Product: kate
Version: 22.08.3
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwrite-bugs-n...@kde.org
Reporter: vidra.jo...@seznam.cz
Target Milestone: ---
Application: kate (22.08.3)
(Compiled from sources)
Qt Version: 5.15.8
Frameworks Version: 5.102.0
Operating System: Linux 6.1.12-gentoo x86_64
Windowing System: X11
Distribution: "Gentoo Linux"
DrKonqi: 5.26.5 [KCrashBackend]
-- Information about the crash:
I opened a text file made by my e-mail client in /tmp. The mail client
auto-deletes the file after waiting a short time for the editor to open it. I
closed the file almost immediately after it opened in the editor, presumably
just as it was being deleted. The "File changed on disk" dialog popped up and
after clicking "ignore", Kate crashed.
The reporter is unsure if this crash is reproducible.
-- Backtrace:
Application: Kate (kate), signal: Segmentation fault
Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = 0x0}
