This should not occur and it is better to find out the root cause, but a crutch is also possible:

from os.path import splitext
from transliterate import slugify

def slugify_upload(instance, filename):
    name, ext = splitext(filename)
    return slugify(name) + ext


class Dancer(models.Model):
    photo = models.ImageFiled(upload_to=slugify_upload, ...)
    ...
