SUMMARY Title, 100% reproducibility STEPS TO REPRODUCE 1. Open system settings 2. Navigate to the thunderbolt page 3. Click on any other page OBSERVED RESULT The settings window closes/crashes EXPECTED RESULT It navigates to the page and doesn't close SOFTWARE/OS VERSIONS Arch Linux: as of 2021-6-26 KDE Plasma Version: 5.22.2 KDE Frameworks Version: 5.83.0 Qt Version: 5.12.2 using X11 ADDITIONAL INFORMATION Tried immediately after a restart, still happened. Also happens even when disconnected from thunderbolt device.
Crashes need a backtrace to be actionable
I haven't made backtraces before, this was hard. I wasn't able to get debug symbols for qt5-base, but I did recompile kcmutils, plasma-thunderbolt and systemsettings.

Dear Bug Submitter, This bug has been in NEEDSINFO status with no change for at least 15 days. Please provide the requested information as soon as possible and set the bug status as REPORTED. Due to regular bug tracker maintenance, if the bug is still in NEEDSINFO status with no change in 30 days the bug will be closed as RESOLVED > WORKSFORME due to lack of needed information. For more information about our bug triaging procedures please read the wiki located here: https://community.kde.org/Guidelines_and_HOWTOs/Bug_triaging If you have already provided the requested information, please mark the bug as REPORTED so that the KDE team knows that the bug is ready to be confirmed. Thank you for helping us make KDE software even better for everyone!
Forgot to change the status, I'm still having the problem with 100% reproducibility.
Looks like it's crashing in teardown.
Happens for me too on: SOFTWARE/OS VERSIONS KDE Neon 5.23 as of 2022-01-22 KDE Plasma Version: 5.23.5 KDE Frameworks Version: 5.90.0 Qt Version: 5.15.3 using X11 I'll add gdb and valgrind output as required by the guidelines.

KCrash: Attempting to start /usr/libexec/drkonqi Alarm clock
The crash is an abort in glibc caused by double free on line 2104 of qt5-qtbase-5.15.3-3.fc36.x86_64/src/corelib/kernel/qobject.cpp 2099 // don't use qDeleteAll as the destructor of the child might 2100 // delete siblings 2101 for (int i = 0; i < children.count(); ++i) { 2102 currentChildBeingDeleted = children.at(i); 2103 children[i] = 0; 2104 delete currentChildBeingDeleted; 2105 } 2106 children.clear(); The comment suggests that when a child deletes a sibling it fails to set that entry in the vector to a null pointer, so that the parent subsequently tries to delete that pointer again.
Created attachment 150185 [details] valgrind log of 'kcmshell5 bolt' Valgrind shows the destruction of the bold module is riddled with bugs, but possibly all caused by one double free. Fixing that might make all the later errors go away.
*** Bug 427516 has been marked as a duplicate of this bug. ***
Code path (presumably) is: - Someone else owns a reference to the device - Manager::~Manager runs. The list clears - QObject::~QObject of the manager runs - We delete a child object owning a reference to the device - We then delete the Device which is a child In any case it's an easy fix.
A possibly relevant merge request was started @ https://invent.kde.org/plasma/plasma-thunderbolt/-/merge_requests/11

Git commit 09c37c1c312991d08c10c7af94a83902150cb3ad by Nate Graham, on behalf of David Edmundson. Committed on 28/09/2022 at 15:44. Pushed by ngraham into branch 'master'. Avoid combining smart pointers and qobject parent ownership Devices are stored as QSharedPointer<Device> mDevices. If something has the memory managed explicitly we don't want QObject parents to also try and do the same job.
