gnome-shell segfault when locking screen
since my recent upgrade to 3.30 gnome-shell crashes with "general protection in libglib-2.0.so.0.5800.1" whenever I try to lock my screen.
from the logs:
[ 3358.411967] traps: gnome-shell[19106] general protection ip:7f0b1d0b9d04 sp:7ffe15228e38 error:0 in libglib-2.0.so.0.5800.1[7f0b1d099000+7d000]
this ist the part of journalctl -al output, that seems relevant:
