I don't do anything odd: I simply modify it by typing in side textarea.
The page has a very simple JavaScript which does not do anything with
the textarea (though I double-checked that turning it off does not
improve the situation). Inspecting the request reveals that the data is
indeed submitted twice (thus django correctly interpret the situation).

The form is using enctype='multipart/form-data' since it is also used to
submit a file, though leaving only the textarea inside the form and
removing the enctype does not help.

I also checked this in both firefox and chrome and both show that the
POST data for this textarea is submitted twice.

Any ideas?

Thanks for help,
Marcin
