Yes. Seems the superscript inset is not properly initialized at that
point, leading to a null pointer in CursorSlice::text().
Note that this is not specific to this particularly inset. I can
reproduce with any other (text) inset, e.g.:
1. Start a new document.
2. Insert a Note inset
3. Save the (new) file (cursor still being in the Note inset).
=> Kaboom.
