Looks likely, would have been nice if we printed it out! ;) I'm curious, is this something rare? Or is it crashing consistently? The former would point to something odd with the values in /proc/<pid>/stat, the latter would point to an issue with our code.
I can send out a fix today, but without being able to reproduce it would simply be ignoring the strange utime / stime values.
