Description Ricardo Bustillo 2025-09-10 19:07:26 UTC

Application: dolphin (23.08.5)

Qt Version: 5.15.13
Frameworks Version: 5.115.0
Operating System: Linux 6.8.0-79-generic x86_64
Windowing System: X11
Distribution: Ubuntu 24.04.3 LTS
DrKonqi: 5.27.11 [KCrashBackend]

-- Information about the crash:
I mounted an USB SSD disk from Dolphin, but I didn't see a new folder I was expecting. So I hit F5 to refresh, and Dolphin closed suddently.

The reporter is unsure if this crash is reproducible.

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

Thanks for the bug report.

However, Plasma 5.27.11 and Dolphin 23.08.5 no longer receive updates or maintenance from KDE; active versions are 6.4.5 (for Plasma) and 25.08.1 (for Dolphin) or newer. Please upgrade to an active version as soon as your distribution makes it available to you. Plasma is a fast-moving project, and bugs in one version are often fixed in the next one.

If you need support for Plasma 5.27.11, 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 Plasma 6.4.5 (the latest released version), feel free to re-open this bug report.

Thanks for understanding.
