Hi. I can't seem to reproduce this on my machine. Could you try this again with all mods (even cosmetic ones) disabled? I'd also appreciate it if you could upload a dump file.
EDIT: Sorry, just saw your edit. I'd still be interested in a dump file here and let us know if it happens again/consistently.
