What is odd is that sometimes the above error doesn't occur, but the CKEditor input field is missing, see Guest_user_No_CKeditor_section.png
The issue reproduces also on XWiki 13.4.5 and 13.4.6. On XWiki 12.10.11 was reproduced only the NPE from the first stacktrace above, after which no other comments can be added.
