.xsession-errors filled with entries

[Brian]

I hope I am in the right place for this. My .xsession-errors file is filled with entries in the following format, in that order/sequence, over and over and continuously:

(nm-applet:1839): Gtk-CRITICAL **: gtk_widget_destroy: assertion 'GTK_IS_WIDGET (widget)' failed

(nm-applet:1839): Gtk-CRITICAL **: gtk_widget_destroy: assertion 'GTK_IS_WIDGET (widget)' failed

(nm-applet:1839): Gtk-WARNING **: Can't set a parent on widget which has a parent

Ubuntu MATE 17.10

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Brian (thwaller)]

I can understand how this may seem like nothing of concern to the devs / maintainers, but when you end up with log files of 15-20MB, and nearly all of it is due to this, it is problemsome. There is no need to see this a handful of times each minute as it just interferes with the actual intention of the xsession-errors file.

[Khurshid Alam (khurshid-alam)]

Please report it to upstream.

[Brian (thwaller)]

I do not know what that means.

[Claudiux (claudiux)]

This kind of message floods the .xsession-errors file:

@ Claudiux (claudiux) - If your comment was for me, I know the issue. I should be more clear, I do not know what this means, or how to do it:

The upstream bug tracker for nm-applet is this one:

https://gitlab.gnome.org/GNOME/network-manager-applet/issues

[Theo Linkspfeifer (lastonestanding)]

However, it this particular issue still present in 18.04 or 18.10?

[Brian (thwaller)]

I can confirm the issue is still there on 18.04 as I am currently running 18.04.1 LTS (Bionic Beaver) 64-bit. I do not use 18.10, so I comment on that.

[Khurshid Alam (khurshid-alam)]

Upstream issue: https://gitlab.gnome.org/GNOME/network-manager-applet/issues/34

[Gabor (gabor-z)]

18.04.1 LTS (Bionic Beaver) 64-bit
Confirm

The first thing I did is to install unity-desktop (not sure the problem existed earlier)

[dn (don-neumann)]

Any movement on this? I'm getting the same issue with gnome flashback with ubuntu 18.04 with latest updates.

[Samuel Dezso Dysch (sdysch)]

Hi, is there any updates for this? I see this issue in xubuntu 20.04 (and previously 19.10). It clogs up the .xsessions-errors file periodically until I run out of disk space. A temporary fix is to write a cron job to empty this file if it exceeds some threshold

[Todd Allen (toddmallen)]

I am encountering the same issue in 20.04. The message is repeating approximately every three seconds, resulting in log files of hundreds of gigabytes. It also makes the system log nearly useless for any other use; it is near-impossible to even open the file, and causes logrotate to hang up for hours every time it attempts to run since it attempts compression.

[Rolf Leggewie (r0lf)]

According to upstream, this is self-inflicted pain in Ubuntu:

+--[ https://gitlab.gnome.org/GNOME/network-manager-applet/-/issues/34#note_860672 ]
|
| I tried the git version of the applet and couldn't reproduce the warnings. After applying
| Ubuntu patches, warnings are present, so this is a downstream issue; please report it to
| Ubuntu bug tracker. In particular, patch Support-hiding-rather-than-desensitizing-disallowed-
| items.patch looks suspicious.
|
+--

[Rolf Leggewie (r0lf)]

My apologies for the fudged linebreak in the previous comment.

I am happy to report that recompiling the bionic packages while disabling Support-hiding-rather-than-desensitizing-disallowed-items.patch from debian/patches/series fixes this issue for me (after logging out of X and logging back in).

[Sebastien Bacher (seb128)]

seems the same issue than bug #1853331 and should be fixed now in groovy
