Syslog is flooded with Object St.Bin (0x565425162c80), has been already deallocated — impossible to set any property on it. This might be caused by the object having been destroyed from C code using something such as destroy(), dispose(), or remove() vfuncs.

Other than the exact line number, this looks close to https://github.com/micheleg/dash-to-dock/issues/1332

Confirmed these are actually the same code:

dash-to-dock docking.js line 2036
ubuntu-dock docking.js line 2051

i found a way to reproduce

- wait for an automatic update manager prompt
- apply the updates (in the dock, the update-manager icon is twisting)
- when its done, close update-manager
- then the error start to appear in syslog

I can confirm #4, triggered by updates. Can be stopped by restarting Gnome Shell.

ALT+F2 r ENTER

Thank you

A fix is available upstream
Can someone make a patch?

The upstream patch works directly.

You just need to apply https://patch-diff.githubusercontent.com/raw/micheleg/dash-to-dock/pull/1366.patch onto /<email address hidden>/docking.js

I've done that locally myself, and it works well.

apt update then apt upgrade fixed the problem for me about four days ago. Thank you for fixing this.

I made a duplicate bug report. The reply to me to post comments here in this bug report instead. The specs for my bug report is here:

This has happened to me twice in the last two days. Until the fix is available, is there any way to recover from it aside from rebooting?

Walt, please tell us the version of Ubuntu you are using.

I'm running Ubuntu 20.10.

But I think I can answer my own question. It just happened again, and this time all I needed to run was run `apt update`. I didn't even install anything! A quick google search found this page: https://www.linuxuprising.com/2020/07/how-to-restart-gnome-shell-from-command.html. I pressed Alt-F2 and then r, and that stopped the logging without a reboot!

I'd still like to know why this suddenly keeps happening. 21.04 is due out in a few weeks and I'm hoping that will fix it.

Yes indeed comment #12 shows the fix is only in 21.04 at the moment.

Need fix in Ubuntu 20.04, gnome-shell-extension-ubuntu-dock 68ubuntu1~20.04.1

Patch in #7 failed 4/4 hunks

Are you sure 20.04 is affected? I can't see any reports of the issue on 20.04.

I've been running 21.10 since it was released and I haven't had the problem on it. I honestly don't recall if I still had the issue on 21.04.

The fix is already in 21.04 and later (comment #12). We're now talking about 20.04.

Sorry I don't check this forum often.

I'm on 20.04.3. When I try to update + upgrade that package, apt tells me I'm stuck with version 68

gnome-shell-extension-ubuntu-dock is already the newest version (68ubuntu1~20.04.1).

The fix is not in Ubuntu 20.04 yet so I will request it. Though if we do a focal update then we should also fix bug 1876641. Maybe more.

gnome-shell[2660]: Object St.Bin (0x5563a04d98d0), has been already deallocated — impossible to set any property on it. This might be caused by the object having been destroyed from C code using something such as destroy(), dispose(), or r>

Still an issue on 21.04 Ubuntu.

21.04 is is not supported anymore, but maybe you meant 22.04?

Regardless, please open a new bug so we can track whatever the more recent cause of the message is:

  ubuntu-bug gnome-shell

I still see this issue on Ubuntu 20.04.4. Has a fix been released for this version of Ubuntu?

It appears the fix only exists in 21.04 and later, of which only 22.04 is currently supported.

A fix has been requested for 20.04 but it seems nobody has had the time yet.

I'm experiencing this in Ubuntu 22.04.3
