Description Roke Julian Lockhart Beedell 2022-06-23 10:43:47 UTC
Application: dolphin (22.04.1)

Qt Version: 5.15.4
Frameworks Version: 5.94.0
Operating System: Linux 5.19.0-0.rc3.20220621git78ca55889a54.28.fc37.x86_64 x86_64
Windowing System: X11
Distribution: Fedora Linux 37 (Rawhide Prerelease)
DrKonqi: 5.25.0 [KCrashBackend]

-- Information about the crash:
I invoked "Open problem data directory" via the consequence of installation of "https://kojipkgs.fedoraproject.org//packages/gnome-abrt/1.4.2/2.fc37/x86_64/gnome-abrt-1.4.2-2.fc37.x86_64.rpm", which "https://koji.fedoraproject.org/koji/buildinfo?buildID=1985530" describes. Dolphin successfully observed approximately 5 of the 7 total directories that were to be invoked, but crashed during invocation of the subsequent 6th directory.

The crash can be reproduced sometimes.

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

New crash information added by DrKonqi

dolphin (22.04.1) using Qt 5.15.4

When "https://gitlab.gnome.org/GNOME/gimp/-/issues/8298" and consequently "https://bugzilla.redhat.com/show_bug.cgi?id=2100443" occurred, Dolphin crashed. The problems occurred simultaneously.

The files that were within each directory.

The actual directories were not duplicated, so their permissions were retained. However, their content is identical.
