I/O operation on closed file

[Tim Sawyer]

Hi,

I'm getting the following error uploading images to my gallery using the admin
site, written in django (full stack at bottom of mail)

ValueError: I/O operation on closed file

It doesn't always happen, and it;s more likely to occur using "Save but keep
editing" in the admin.

I'm using svn 10712.

Any clues?

Thanks,

Tim.

This is probably a symptom of http://code.djangoproject.com/ticket/11084 .

Thanks Alex.

I've just updated to 10784 (without a fix for that bug) and it seems fine now!

Cheers,

Tim.
