Ticket resolved as incomplete, because no answer in a reasonable amount of time (1+ year), if it still happens, please update the ticket.

The issue is fixed. Not sure when exactly, but I wasn't able to reproduce it in 1.12. I ran a second test in 1.7.5 with the same world under the same circumstances and the game crashed as mentioned by the reporter. So really is about this issue.
