gnome-shell crashes after using pan
Gnome-shell crashes while using pan newsreader, and takes the login session down with it. I see XWayland crash also happening around that time (gnome-session doesn't seem to crash).
Sometimes gnome-shell crashes while reading the news, sometimes it survives until exiting pan, but I can semi-reliably get this defect after a pan session longer than just starting it up and exiting.
I filed a Fedora bug https://bugzilla.redhat.com/show_bug.cgi?id=1539992 with stack trace from coredumpctl because I am a newbie with the Gnome gitlab, but now that I seem to be logged in, I will enclose few stack dumps here as well.
while getting those stack traces, coredumpctl complains that it's missing files File "/var/lib/systemd/coredump/core.Xwayland.1000.bbc4e6c3d3694c6cb5a31d420f3fce11.30493.1515991347000000.lz4" is not readable: No such file or directory
