Failed to load libcanberra-gtk-module.so

[skrisman]

Binary package hint: python-visual

To reproduce this bug follow these steps:

$ python
>>> from visual import *
>>> sphere()

The error that will initially spit out is:
Gtk-WARNING **: Failed to load module "libcanberra-gtk-module.so": libcanberra-gtk-module.so: cannot open shared object file: No such file or directory
<visual.primitives.sphere object at 0xb7e05c84>

if you try to ctrl-d or ctrl-c out of it you will recieve errors. On top of that if your using gnome-terminal and you ctrl-c out of the interpreter the terminal will become unusable. The bug makes it so that the screen that pops out paints in weird ways and can't be moved without leaving a "ghost" screen in its initial place. In addition it always paints as the top window.

There is no libcanberra-gtk-module.so in /usr/lib but curiously there is a copy in /usr/lib/gtk-2.0/modules. I tried to create a symbolic link to that module and I didn't recieve any warning, instead I recieved a segmentation fault.

I was trying to reproduce this bug to confirm it since I get the same error with other packages (not with python-visual) but can't get python visual to work this package dependencies seem not handled properly:

it required numarray (wasn't installed) or numeric (was installed):
>>> from visual import *
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.6/dist-packages/visual/__init__.py", line 15, in <module>
    import array_backend
  File "/usr/lib/python2.6/dist-packages/visual/array_backend.py", line 50, in <module>
    raise RuntimeError, "Neither Numeric nor numarray could be found."
RuntimeError: Neither Numeric nor numarray could be found.

Then after having installed numarray:
>>> from visual import *
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.6/dist-packages/visual/__init__.py", line 24, in <module>
    import crayola
ImportError: No module named crayola

I cannot find crayola in my packages...

Same behavioru as the first post:

Ubuntu Jaunty up to date, with backports, 64bit,
Linux muizenberg 2.6.28-15-generic #52-Ubuntu SMP Wed Sep 9 10:48:52 UTC 2009 x86_64 GNU/Linux
ii python-visual 3.2.9-4.1build1 VPython 3D scientific visualization library

1 jan@muizenberg:~$python BallPro.py

Gtk-WARNING **: Failed to load module "libcanberra-gtk-module.so": libcanberra-gtk-module.so: cannot open shared object file: No such file or directory
0 jan@muizenberg:~$locate libcanberra-gtk-module.so
/usr/lib/gtk-2.0/modules/libcanberra-gtk-module.so
/usr/lib32/gtk-2.0/modules/libcanberra-gtk-module.so

And if I symlink from /usr/lib to /usr/lib/gtk-2.0/modules/libcanberra-gtk-module.so
then I get a segmentation fault.

When run from ipython, using %run BallPro.py, the same error displays,
and closing the vpython window exits completely from ipython.

Is this still a issue in recent versions (12.04+) of Ubuntu?
