FileField bug

[Dagur Páll Ammendrup]

I get this error: ​http://django.pastebin.com/344429 When I try to create a new message with an attachment. But still the object is created and the file seems to be added to my media directory.

However, if I create the message first and then edit it, adding the attachment, I get no errors and no problems.

The model validates and I'm using revision 547.
here is my model: ​http://django.pastebin.com/344456

My initial attempt to fix it is ​here, but this brought up ​this error when Dagur tried to edit it in admin

Changing the pre_save method in django/core/meta/fields.py to this did the trick (and as far as I can see it doesn't break anything):

    def pre_save(self, value, add):
        if self.auto_now or (self.auto_now_add and add) or value=='':
            return datetime.datetime.now()
        return value

I assume this is fixed by now, so I'm closing...
