unicode problems in admin interface

[Jaap van Wingerde]

I have suddenly unicode problems with de admin interface:

"DjangoUnicodeDecodeError at /admin/art/photographextra/

'ascii' codec can't decode byte 0xc3 in position 32: ordinal not in
range(128). You passed in <exposition: [Bad Unicode data]> (<class
'art.models.exposition'>)
...
Unicode error hint

The string that could not be encoded/decoded was: l>Mus��e du"

The site itself is behaving well:
<http://glaskunst.liakoster.nl/expositie/medium-verre-21/>.

settings.py:
"...
INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'grappelli.dashboard',
    'grappelli',
  # Uncomment the next line to enable the admin:
    'django.contrib.admin',
    # Uncomment the next line to enable admin documentation:
    'django.contrib.admindocs',
    'art',
    'rosetta',
    'dbgettext',
)
...
DEFAULT_CHARSET='utf-8'
FILE_CHARSET='utf-8'
DEFAULT_CONTENT_TYPE='text/html'
..."

"jaap@liakoster:/var/django/liakoster.nl/test2$ python -c "import
django; print(django.get_version())" 1.7
jaap@liakoster:/var/django/liakoster.nl/test2$ python -V
Python 2.7.3
jaap@liakoster:/var/django/liakoster.nl/test2$"



What is going on?
