Bug#836301: mate-panel: Applets from mate-panel spam logfiles after gtk-3 update

Package: mate-panel
Version: 1.14.2-1
Severity: normal

Dear Maintainer,

I'm not really sure whether I picked the correct package to report this bug,
but at least all errors I get are from mate-panel applets.


Everything started yesterday after I updated these files:

gir1.2-gtk-3.0 (3.20.9-1) to 3.21.5-1
gtk-update-icon-cache (3.20.9-1) to 3.21.5-1
libgail-3-0 (3.20.9-1) to 3.21.5-1
libgtk-3-0 (3.20.9-1) to 3.21.5-1
libgtk-3-bin (3.20.9-1) to 3.21.5-1
libgtk-3-common (3.20.9-1) to 3.21.5-1
libgtk-3-dev (3.20.9-1) to 3.21.5-1

I downgraded again to 3.20.9-1. Today, there was another update (3.21.5-3), but
the issue remained. The log entries are from that latest version.

After installing these packages and executing "mate-panel --replace &>/dev/null
&", /var/log/syslog was immediately cluttered with countless repetitive
messages (about 1.6 MB spam after not even 15 minutes). The attached file
contains the snippet from /var/log/syslog immediately after restarting mate-
panel (on up- and on downgrade).

The applets still work, but such a spammed log file is not very useful as it is
hard to find the important stuff among these messages. Is there anything I
could to except keeping the culprit packages on hold?

Best regards

Andreas
