Description Jehan 2017-12-02 00:00:10 UTC
GNOME/Wayland from Fedora 27.

When the crash happened, no specific application was opened, I was simply testing a Wacom tablet buttons (I just mapped some letters to a button and was clicking them in a terminal to see if they appeared).
Then it crashed after a few minutes.

Comment 1 Jehan 2017-12-02 00:03:42 UTC
Changing component to Xwayland since the original crash seems to have happened there.
Also setting to critical since it crashes GNOME and everything in it.

Moreover I am not sure at all there is any relation with Wacom. That's just what I was doing at the time (testing Wacom buttons) but there don't look to be anything related to it in the backtraces.
Comment 2 Olivier Fourdan 2017-12-04 10:09:37 UTC
Could you please install the relevant debuginfo packages for Xwayland and post the output of "bt full" in gdb?

For my own reference, I installed the debuginfo with:

> sudo dnf debuginfo-install /usr/bin/Xwayland

The output:

Thanks!

From within gdb, can you please do:

(gdb) f 9
(gdb) p *xwl_seat
(gdb) p *xwl_cursor

And copy/paste the result of those 3 commands above in here?
