Thanks for the bug report. Can you reproduce this segfault? Can you post some information about your drive? Manufacturer, type.
I can confirm that this problem went away after I successfully removed and reinstalled the drive on my laptop. The connector appears to have been loose, and the intermittent connection led to this fault occurring during use.
Thanks.
