What happens is this: In https://invent.kde.org/network/kdenetwork-filesharing/-/blob/master/samba/filepropertiesplugin/qml/ACLPage.qml#L249 we call sambaPlugin.permissionsHelper.reload() In reponse to that in https://invent.kde.org/network/kdenetwork-filesharing/-/blob/master/samba/filepropertiesplugin/permissionshelper.cpp#L35 we call job->exec(), which spawns a nested event loop If the user then closes the window while the job has not finished we destroy the QML view, which crashes with "Object %p destroyed while one of its QML signal handlers is in progress.\nMost likely the object was deleted synchronously (use QObject::deleteLater() instead), or the application is running a nested event loop" Since the job usually finishes very fast it's hard to reproduce, but it can be triggered by adding a sleep() in the statjob impl A possibly relevant merge request was started @ https://invent.kde.org/network/kdenetwork-filesharing/-/merge_requests/38 Git commit 5a1111098277128482b77f28c8c08f3f88f606d7 by Nicolas Fella. Committed on 01/01/2023 at 23:01. Pushed by nicolasfella into branch 'master'. Don't exec() the StatJob exec() spawns a nested event loop, which is very problematic In particular here it causes a crash when the job is running when the window is closed By using coroutines and QCoro we can achieve the API convenience of exec() without using nested event loops M +1 -0 .kde-ci.yml M +5 -1 CMakeLists.txt M +1 -0 samba/filepropertiesplugin/CMakeLists.txt M +18 -7 samba/filepropertiesplugin/permissionshelper.cpp M +3 -0 samba/filepropertiesplugin/permissionshelper.h https://invent.kde.org/network/kdenetwork-filesharing/commit/5a1111098277128482b77f28c8c08f3f88f606d7 |
