Please send the information from `reportbug --template gnome-shell` so that we know which dependencies are up to date with unstable and which are not. > #0 0x00007fba077bed12 in g_type_check_instance_cast > (type_instance=0x5583678164b0, iface_type=94022861577152) at > ../../../../gobject/gtype.c:4057 > is_instantiatable = <optimized out> > check = <optimized out> > #1 0x00007fba04f2b998 in st_label_set_text (label=0x558368173c60 [StLabel], > text=0x55836ac42850 "44°C") at ../src/st/st-label.c:331 > priv = 0x558368173800 > ctext = <optimized out> > __func__ = "st_label_set_text" Source code of line 331: ctext = CLUTTER_TEXT (priv->label); Something in JavaScript code (we can't tell what) is calling set_text() on a StLabel at a time when its associated ClutterText is a dangling pointer or has already been freed; and it is setting the label to "44°C". If this happens when the screen locks, then I suspect an extension might not be getting unloaded correctly. The mention of a temperature makes me wonder about gnome-system-monitor. Which GNOME Shell extensions, if any, do you have enabled and installed? Please run: dconf read /org/gnome/shell/enabled-extensions ls ~/.local/share/gnome-shell/extensions ls /usr/share/gnome-shell/extensions Jakobus: please do the same? Thanks, smcv
