OK - I'll do so.

Dam it - I read horizontal and not vertical... Makes sense.

In the life session, I get the following: (as I continued some editing,
the position might be off compared to the session which crashed)
,----
| Text content at position 34253:
|
|
| There is an overlay here:
| From 34252 to 34259
| evaporate t
| face flyspell-duplicate
| flyspell-overlay t
| help-echo "mouse-2: correct word at point"
| keymap [Show]
| mouse-face highlight
|
|
| There are text properties here:
| fontified t
| line-prefix [Show]
| org-category "EnergyBalance"
| org-stats 77
| wrap-prefix [Show]
|
| [back]
`----
and for describe-face when the cursor is in the "ownFree" as above I get:
,----
| Face: flyspell-duplicate (sample) (customize this face)
|
| Documentation:
| Flyspell face for words that appear twice in a row.
| See also ‘flyspell-duplicate-distance’.
|
| Defined in ‘flyspell.el’.

I leave the session as it is to provide further info.
