Created attachment 189978 [details] journald log dolphin SIGSEGV corefile messages This dolphin crash may have occurred during a user logout from the Kde desktop.
Thank you for the bug report. I'm not able to reproduce this on Dolphin built from git-master (also using cli arguments to open a folder). Unfortunately the backtrace is incomplete and missing debug symbols for the following lines that we need to figure out exactly what's going wrong: #12 0x00007fd6c145c26f n/a (libQt6Widgets.so.6 + 0x25c26f) #27 0x00007fd6c0237e86 n/a (libQt6Core.so.6 + 0x237e86) Could you please install debug packages and attach a new symbolicated backtrace generated by using `coredumpctl gdb` in a terminal window? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl for details about how to do this. Thanks again!

Git commit 2dce7352c1edfb13c90a8a3b858d113e3a9300b2 by Méven Car, on behalf of Wendi Gan. Committed on 26/04/2026 at 09:42. Pushed by meven into branch 'master'. Fix occasional UAF crashes in KConfig::sync() during exit Previously, c035e95 introduced `QtConcurrent::run` to execute `KConfig::sync()` in a separate thread. However, this introduced thread-safety issue: BUG 518433 (UAF caused by RC): During application exit, the main thread frees the old `s_sessionConfig` in `KMWSessionManager::saveState()` to create a new one. Meanwhile, the worker thread is still iterating over the old instance's entryMap during `KConfig::sync()`, leading to a Use-After-Free (UAF) crash. Changes: Copy the `config` in the main thread so `KConfig::sync()` can safely run in the worker.
