 Rwanda's OS5, based on 11.3.0-XO-1.5 goes through runin and final
 correctly, but is failing to boot at the QA stage.

 We have logs for 3 units -- see attachments.

 The logs seem to be identical, and the failure symptom is that prefdm
 fails to start Sugar. Python segfaults with:

 segfault at 9fa8000 ip a6fc5e2e sp afe19c20 error 4 in
 libglib-2.0.so.0.2600.0[a6f80000+10d000]

 We have been unable to repro this just performing fs-update on a fresh
 XO-1.5 unit, so we are investigating whether this may be related to the
 microSD card (batch, wear after runin), QSMC environmental factors, runin
 bugs, etc.

 Interactions between mfg date and boot date have been investigated and
 ruled out.
