Failed to load module "atk-bridge" and "canberra-gtk-module"

[_z0rk_]

Pale Moon Version: 27.6.2 (32-bit)
4.9.0-4-amd64 GNU/Linux
Gnome Version 3.22.2
Debian GNU/Linux 9.2 (stretch)

Installed by: https://software.opensuse.org/download. ... e=palemoon
Installed: libcanberra-gtk-module 0.30-3, libatk-bridge2.0-0 2.22.0-2

Starting Pale Moon from CLI generates failed to load module "atk-bridge" and "canberra-gtk-module" errors.
What would cause this?

Thanks!

The same Pale Moon starts on the Stretch-based MX 17 beta without any error or warning messages at all, but it has a lot of packages and libraries installed by default, so one or more of them must get rid of them. Using aptitude to search for installed packages with "atk" or "canberra", and extra info removed:

Code: Select all

$ aptitude show '?and(?name(atk), ~i)'

Package: libatk-wrapper-java             
Package: libatkmm-1.6-1v5
Package: gir1.2-atk-1.0
Package: libatk-wrapper-java-jni
Package: libatk1.0-0
Package: libatk-bridge2.0-0
Package: libatk1.0-data

Code: Select all

$ aptitude show '?and(?name(canberra), ~i)'

Package: libcanberra-gtk-module          
Package: libcanberra-gtk3-module
Package: libcanberra-pulse
Package: libcanberra-gtk3-0
Package: libcanberra-gstreamer
Package: libcanberra-gtk0
Package: libcanberra0

All packages except libcanberra-gstreamer were already installed. Installing this last missing package did not resolve the errors. Oh well...

Thanks for your suggestion though.
