Document has three pages, facing pages starting right. Deleting page 3 without problem, deleting page 1 leads to instant crash.
There is no problem deleting pages, when I change the document to non-facing pages.
Edit: Noticed by the way. When there is only one page left you are not allowed to delete this page, but the trash can indicates that you can delete this page, so the trash can should be deactivated in this case.
