I don't see anything here that looks like a retrace failure. I assume it was marked as such on the retracer, but why?

The Ubuntu Error Tracker is still experiencing some failures when
trying to retrace armhf crashes from Utopic. The retracers for the

using apport-retrace. Here is the output from gdb with 'set debug
