*** Bug 394304 has been marked as a duplicate of this bug. *** *** Bug 393189 has been marked as a duplicate of this bug. *** Git commit 56382f8d9a80796a21d7087ddb660519fbbb5c2e by David Edmundson. Committed on 16/05/2018 at 09:21. Pushed by davidedmundson into branch 'master'. Process DBus replies in the ::match thread Summary: 6114612970bcf757d9e06a623d6220257ce57b5f turned the DBus requests into using QDBusPendingCallWatcher but blocking so that it's still handled within the ::match() method. However, it accidentally processed replies in the main thread, rather than in the match thread which wasn't the intention. Result is occasional threading related crashes. Test Plan: Still had results from baloo (one of our DBus runners) It didn't crash (but it never crashed for me before either) One tester replied: [10:00] <sunnyflunk> d_ed: looks good, tried 30 times with patch and no crash, then turned off the patch and crashed 4th time Reviewers: #plasma, broulik Reviewed By: #plasma, broulik Subscribers: kde-frameworks-devel Tags: #frameworks Differential Revision: https://phabricator.kde.org/D12924 M +1 -1 src/dbusrunner.cpp https://commits.kde.org/krunner/56382f8d9a80796a21d7087ddb660519fbbb5c2e *** Bug 394697 has been marked as a duplicate of this bug. *** *** Bug 394919 has been marked as a duplicate of this bug. *** *** Bug 394989 has been marked as a duplicate of this bug. *** *** Bug 395099 has been marked as a duplicate of this bug. *** *** Bug 394527 has been marked as a duplicate of this bug. *** *** Bug 394320 has been marked as a duplicate of this bug. *** *** Bug 395114 has been marked as a duplicate of this bug. *** *** Bug 395120 has been marked as a duplicate of this bug. *** *** Bug 395134 has been marked as a duplicate of this bug. *** Created attachment 113223 [details]
New crash information added by DrKonqi
plasmashell (5.12.5) using Qt 5.10.0
- What I was doing when the application crashed:
Launching the Application Menu and starting a research, then plasma shell crash.
I have this crash approximatively 4 times a day.
