Package: gnome-shell
Version: 3.26.2-3
Severity: normal
---- Introduction ----
Versions of gnome-shell prior to 3.26.2-3 have some issues where an
invalid pointer to a destroyed object gets used, for example #881301.
This affects some users more than others, depending on use patterns.
In 3.26.2-3 I've made gnome-shell depend on a version of gjs where this
situation is handled a bit more gracefully, with warnings logged to the
systemd journal when it happens. This is still a bug, but it's a less
serious bug than crashing the Shell.
If other gnome-shell users see warnings similar to what I've quoted in
this bug report, but with a different stack trace, please report each
different stack trace as a *separate* bug report, otherwise we will
get hopelessly confused. Please make sure to report which extensions,
if any, you have enabled.
These bugs can usually be fixed by disconnecting from signals when an
object emits the destroy signal, similar to this upstream issue report
and fix in the pomodoro extension:
https://github.com/codito/gnome-pomodoro/issues/320
Depending where the root cause is, it might require changes to
gnome-shell itself, or changes to an extension.
---- Bug report ----
I get matching stack traces for different objects in both the gdm
greeter, and the gnome-shell running as me. The gdm greeter never has any
extensions enabled. My gnome-shell currently has the caffeine extension
and no others.
