RuntimeError: dictionary keys changed during iteration

[jpic]

With this code:

class Industry(TranslationModel):
    name = models.CharField(max_length=255)
    profession_set = models.ManyToManyField(
        'Profession',
        through='IndustryProfession',
    )

    def __str__(self):
        return self.name

    class Meta:
        translatable_fields = ('name',)

Getting a shell exception:

In [5]: Industry.objects.language('fr').filter(name='Armement')

RuntimeError: dictionary keys changed during iteration

Not sure what I'm doing wrong, also got some weird results here:

In [14]: Industry.objects.filter(name='Armament').first().translations                                                                              
Out[14]: {'name': {'en': 'Armament', 'fr': 'Armement'}}

In [15]: test = Industry.objects.filter(name='Armament').first()                                                                                    

In [16]: test.language('fr')                                                                                                                        
Out[16]: <Industry: Armament>

In [17]: test.name                                                                                                                                  
Out[17]: 'Armament'   <-------------- not the fr translation

#42 should fix this.
