Bug#1094442: libgtk-3-0t64: Panels crash under Wayland

[Fiona Klute]

Package: libgtk-3-0t64
Version: 3.24.48-3
Severity: important

After update from 3.24.43-5 to 3.24.48-3 xfce4-panel (in xfce-wayland
session) started crashing when simply right-clicked, and some panel
items also crashed on left-click. Logs show a segfault (I run
xfce4-panel via systemd user session):

I first suspected a bug in the experimental Xfce Wayland support (though
I've been using it without major issues for a while), but when I tried
Waybar as a possible workaround it showed the same behavior: Right-click
the bar, segfault.

(Speicherzugriffsfehler -> segmentation fault)

Downgrading the installed gtk+3.0 packages (list below) to 3.24.43-5
made the problem go away.

gir1.2-gtk-3.0
libgail-3-0t64
libgtk-3-0t64
libgtk-3-bin
libgtk-3-common
libgtk-3-dev

Thanks!
