As it seemed to have to do with dimensions I tried and deleted everything on the dimension layers by pulling up a window or "delete all". I then deleted the "sideview" layer and then could save the file without a crash. But I noticed afterwards (and repeated the process to be sure) that deleting the dimensions also removed the inserted block on the "New.4912.outline" layer.
So it seems there are invisible cross-connections from entities on some layer to alien layers. Weird again.

The file seems to be rather screwed up and I don't know how to fix it. I have tried and copied the contents into a new file. At first look it seemed to work, but at repeated opening the problems returned.
I give up on this.
