--- Comment #35 from Claus Prüfer <prue...@webcodex.de> ---
Since my KDE Bug reporting tool still hangs on final bug-submission (no way of
getting entered text back), i have to repeat the bug-reporting without a
back-trace attached. Also i can not find where the core-dump has been saved
locally.
The application (KDevelop) crashed with a Segmentation Fault (core-dumped),
this is an indicator that some sort of null-pointer, double-free or similar has
happened (in kernel).
Since the bug occurred repeatedly on my systems multiple times, regardless of
Linux-System, Windows Manager (X11 and Wayland), Graphics Driver (Intel, Nuveau
or compiled NVIDIA drivers), i assume the cause is to find somewhere in "Mouse
/ Keyboard" interface handling of involved interfaces (Kernel / QT / KDE Base /
Kate), maybe in combination with source-code highlighting update / triggering
(indicator in first comment / back-trace: "KDevelop::TextDocument::reload()" or
"QAccessibleEvent::accessibleInterface()").
Also the crash happened multiple times after my mouse-cursor got laggy in
Firefox-browser (maybe interrupt handling / network interface card / malware).
The case the same crash occurred on internet-less setup multiple times excludes
the malware suspect (but do not underestimate malware creators).
All back-traces include "QAccessibleEvent::accessibleInterface()" and
"QAccessible::updateAccessibility(QAccessibleEvent*) () and
KateViewInternal::cursorMoved()".
Additionally i can report that i clicked the mouse accidentally multiple times
quite fast, this could be an indicator that somewhere a queue processing
(threaded?) contains too much or too less pointers or pointers to already
deleted memory (maybe time dependent too).
As already mentioned, the occurrence is Linux independent, but to complete
information:
Operating System: Devuan GNU/Linux 5
KDE Plasma Version: 5.27.5
KDE Frameworks Version: 5.103.0

Hopefully i could help finding the bug.
