gnome-shell crash on opening pdf attachment
See coredumpctl gdb
log below. Wayland crashes every few days for me.
I can't pin-point a pattern: The log below is because it crashes trying to open a pdf attachment in Thunderbird (using
the default Document Viewer). After rebooting, the same attachment opened with no problems.
I'm running an updated Fedora 27 on an HP Spectre. I have a 4k Sceptre monitor (cheap and possibly buggy) connected via a Thunderbolt-3-to-HDMI dongle - or maybe it's a USB-C-to-HDMI dongle :-) .
