I am changing this back to "verification-done" even though bug 1447295 has not yet been root caused. My justification is:
1) I attempted and failed to reproduce the possible regression reported in bug 1447295.
2) The failure mode in 1447295 looks more consistent with a bug in sed or (more likely) an intermittent hardware failure (sed crashes with an Illegal instruction)
3) The only change made to the GRUB source is the addition of a dependency for a different architecture than the system in bug 1447295.
4) Attempts at completing root cause analysis of bug 1447295 have been stalled for >10 days awaiting feedback from the reporter.
