[yocto] hob issues

[Dallas Clement]

I've having some difficulty running hob on Debian "wheezy/sid".  When
I enter "hob" from the command line, an X-window opens, but none of
the controls have any text labels.  Also, none of the drop-down lists
are populated.

I also see this message on the command prompt:

Gtk-Message: Failed to load module "canberra-gtk-module"

I installed libcanberra-gtk3-0, which didn't make any difference.

Is there anything else I should try?
