Application: kinfocenter (5.11.3) Qt Version: 5.9.2 Frameworks Version: 5.40.0 Operating System: Linux 4.14.2-1-default x86_64 Distribution: "openSUSE Tumbleweed" -- Information about the crash: - What I was doing when the application crashed: Switching between OpenGL, X-Server and Wayland tab leads to this crash. If you click once on all three in about 50% of the cases it crashes. All similar bugs are marked as a duplicate of 372597, however this is marked as resolved since June - which is obviously wrong. The crash can be reproduced sometimes. -- Backtrace: Application: Info Centre (kinfocenter), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".

Created attachment 109934 [details] New crash information added by DrKonqi kinfocenter (5.12.80) using Qt 5.10.0 - What I was doing when the application crashed: I can confirm this reliably. The crash happens here only when switching to any Info Center module _after_ the "Graphical Information" > "Wayland" module. -- Backtrace (Reduced): #6 0x00007f742a3d1bc9 in wl_map_insert_at (map=<optimized out>, flags=flags@entry=0, i=<optimized out>, data=<optimized out>) at /var/tmp/portage/dev-libs/wayland-1.13.0/work/wayland-1.13.0/src/wayland-util.c:249 #7 0x00007f742a3cdebe in proxy_destroy (proxy=0x55e64b5c4db0) at /var/tmp/portage/dev-libs/wayland-1.13.0/work/wayland-1.13.0/src/wayland-client.c:411 #8 wl_proxy_destroy (proxy=0x55e64b5c4db0) at /var/tmp/portage/dev-libs/wayland-1.13.0/work/wayland-1.13.0/src/wayland-client.c:442 #9 0x00007f7428f1c645 in wl_registry_destroy (wl_registry=<optimized out>) at /usr/include/wayland-client-protocol.h:1065 #10 KWayland::Client::WaylandPointer<wl_registry, wl_registry_destroy>::release (this=0x55e64b533e70, this=0x55e64b533e70) at /var/tmp/portage/kde-frameworks/kwayland-9999/work/kwayland-9999/src/client/wayland_pointer_p.h:53
I can confirm this issue on openSUSE Tumbleweed with Qt 5.10.0 and kwayland from git master (07935f7). Assigning to the creator of the wayland info module in kinfocenter.

patch at: https://phabricator.kde.org/D10391 The regression was caused by a change in libWayland. We had similar crashes unfortunately in other areas as well.
Git commit a7e887975d0181d9039e3d727b0f8172b0bfc2e3 by Martin Flöser. Committed on 08/02/2018 at 17:59. Pushed by graesslin into branch 'Plasma/5.12'. Ensure Registry gets destroyed before the Wayland connection Summary: Registry was parented to WaylandModule, but the ConnectionThread got destroyed in the dtor, thus before the Registry resulting in a crash when the Registry got destroyed. This change addresses this problem by tracking the Registry and destroying it before destroying the Connection.
