Tried using LibreOffice 5.0.3 rc2, 2015-11-03-nightly, and 4.4.6.3, all with the same result.
I've tried:
- Deleting my user profile
- Upping the Memory settings
- Opening the file on an Ubuntu 14.04 VM (it opened immediately)
- Opening the file on a Windows 8.1 VM (opened immediately)
Aside from those attempts, I've found nothing that might indicate why this is happening.
If you want the file, you can get it from the bugzilla page here: https://bugs.documentfoundation.org/show_bug.cgi?id=95588
