Description Paul 2025-09-07 19:26:48 UTC

Application: dolphin (23.08.5)

Qt Version: 5.15.13
Frameworks Version: 5.115.0
Operating System: Linux 6.8.0-78-generic x86_64
Windowing System: X11
Distribution: Ubuntu 24.04.2 LTS
DrKonqi: 5.27.11 [KCrashBackend]

-- Information about the crash:
Previous versions of dolphin closed the tab when a usb drive was ejected, now it shows an orange error bar saying the location is no longer available. Worse than that it crashes out completely occasionally and seems to think some of my internal ssd's are being removed - which they are not, obviously. I've gone from a stable 22.04 to a shaky 24.04 and this is on both my desktop pc and laptop.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault

Hi, I'm afraid Dolphin 23.08.5 no longer receives updates or maintenance from KDE; active versions are 25.04.3 or newer. Please upgrade to an active version as soon as your distribution makes it available to you, or use other application distribution methods such as Flathub. Dolphin is a fast-moving project, and bugs in one version are often fixed in the next one.

 If you need support for Dolphin 23.08.5, please contact your distribution, who bears the responsibility of providing help for older releases that are no longer receiving updates from KDE.

If this issue is still reproducible in a supported version of Dolphin, feel free to re-open this bug report.

Thanks for understanding!

New crash information added by DrKonqi

dolphin (23.08.5) using Qt 5.15.13

Bug report wizard indicated that the issue experienced is a duplicate of a bug 509247 which happens when usb driver is ejected. In my case no USB drive was ejected. Usb devices connected were a mouse receiver and a USB-C laptop charger.

The crash happened when I wasnt interacting with Dolphin at all. I had just opened TravingView snap package/app and waiting for it to load when Dolphin crash handler appeared. Other active apps open were Brave browser, kate text editor, background apps Telegram, MEGAsync, Tuxedo Control Center.

As I mentioned in my last reply, if you need support for Dolphin 23.08.5, please contact your distribution, who bears the responsibility of providing help for older releases that are no longer receiving updates from KDE. Thanks.
