Typing the above in ipython here works on Fedora 15 with:
gtkmm24-2.24.0-3.fc15.x86_64

I'd say it's a problem in gtk so I'd file a bug against that in ubuntu.

Here I had a problem with umlauts in filenames:
In [1]: from visual.filedialog import get_file
The Polygon module is not installed,
   so the text and extrusion objects are unavailable.
The ttfquery and/or FontTools modules are not installed,
   so the text object is unavailable.

In [2]: fd = get_file()

UnicodeDecodeError                        Traceback (most recent call

----> 1 fd = get_file()

/usr/lib64/python2.7/site-packages/vis/filedialog.pyc in
get_file(file_extensions, x, y, title, mode, maxfiles) 26
file_extensions = [file_extensions] 27     return
filedialog(file_extensions=file_extensions, ---> 28
x=x, y=y, title=title, mode=mode, maxfiles=maxfiles) 29 
     30 def filedialog(file_extensions=None, x=100, y=100,
title="Open", mode='rU', maxfiles=20):

    155             labels[n].color = lcolor
    156 

UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position
12: ordinal not in range(128)

But when avoiding such directories, it works.
