Hi Christopher, Thanks for your response. Actually in the end I re-installed a debian system, so I can't really help with any more diagnostics from the system that was having the problem.
I can report that I'm not seeing this crash on the same laptop with the 3.16.0-4-amd64 kernel and Debian Jessie installed. I'll notify here if it reaapears in Debian, too.
