Description:
I "created" the category "Wikimedia CH" by inserting an article into it.
Afterwards I went to the category-page to write a little description of the
category. When opening the edit-page, there was the usual "This page doesn't
exist yet"-text and afterwards in red and bold/italics:

"Sorry! We could not process your edit due to a loss of session data.

Because this wiki has raw HTML enabled, the preview is hidden as a precaution
against JavaScript attacks.
If this is a legitimate edit attempt, please try again. If it still doesn't
work, try logging out and logging back in."

Below that was the normal edit box. When typing in a text and saving it,
everything worked fine, when opening the edit page again afterwards, the warning
has disappeared.

This pattern can be seen at all non-created category pages on internal-wiki (try
out http://internal.wikimedia.org/w/index.php?title=Category:foo&action=edit),
but after a quick look, this bug seems not to exist when doing the same e.g. at
enwp.
