Just launching and closing GIMP causes the following error:
$ LANG=C gimp
Gtk-Message: Failed to load module "canberra-gtk-module":
libcanberra-gtk-module.so: cannot open shared object file: No such file
or directory

It repeats sometimes during execution. Installing libcanberra-gtk-module
solves.

Marking this as minor, as I can't see an actual problem this causes
(there is no crash).

This is probably due to having libcanberra-gtk0 installed, which already
recommends libcanberra-gtk-module.

It isn't, thanks for reopening.

Do you have this issue with any other GTK programs?

Good point, looks like I do. I use KDE and don't have many GTK+
applications installed, but this is the output just launching and
closing FileZilla:

$ LANG=C filezilla
Gtk-Message: Failed to load module "canberra-gtk-module":
libcanberra-gtk-module.so: cannot open shared object file: No such file
or directory

Same issue described before with libgtk2.0-0.

I would get the following when running applications from a terminal
(gimp, hexchat, xsane, ...):
Gtk-Message: 16:08:13.676: Failed to load module
"libcanberra-gtk-module"

Installing libcanberra-gtk-module solved the issue.

BTW, the problem was not found with filezilla, which depends on
libgtk-3-0, probably because libcanberra-gtk3-module was already
installed on my system.

Thanks!

Tassia.
