*** Bug 420516 has been marked as a duplicate of this bug. *** > Qt Version: 5.9.8
>_Frameworks Version: 5.60.0
Is this reproducible with more recent versions ?
Can't really say for the time being, I'm more or less locked in to Qt 5.9 but as soon as I figure out how to trigger this I'll try with the KDevelop AppImage. Application: kdevelop (5.5.0-28-g20dd819cea) (Compiled from sources) Qt Version: 5.9.8 Frameworks Version: 5.60.0 Operating System: Linux 4.14.23-ck1-mainline-core2-rjvb x86_64 Windowing system: X11 Distribution: Ubuntu 14.04.6 LTS -- Information about the crash: - What I was doing when the application crashed: Another crash like this, quite a bit after I exited from a KDevelop session. From the looks of it, a timer fires that is connected to a KDirLister job, which is apparently still alive (after the core cleanup routine exited?!) but which has a stale reference to an associated KJobWidget. I'll try to look into this, but if my analysis rings any bells please tell me where I could start looking. Could this be a side-effect of the somewhat recent change where on-disk changes are handled through a timer instead of queued immediately? -- Backtrace: Application: KDevelop (kdevelop), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Report to https://bugs.kde.org/ The only use of KDirLister I could find that might explain this crash is in the filemanager plugin. It's a bit early to confirm, but I haven't seen any of these crashes since running the patch below (which in any way shouldn't hurt). If I do get another of these crashes I should be able to see whether this dirlister is the culprit, at least.
