This bug was filed from the Socorro interface and is 
report bp-0c5e2edd-fbb0-4aae-9297-d74f22140608.
=============================================================

This startup crash started showing up this week in the list of explosive reports for nightly 32.0a1 (https://crash-analysis.mozilla.com/rkaiser/0000.overview.html). It's not a recent signature, as it exists in 29 and 30, for example, but it had a spike this week.

Mostly happening in Win7 installations, but it happens in all platforms.

The spike on 32.0a1 appears to have all come from the same user. In those reports the top frames are garbage, so we don't have much information to go on.

Since 32.0a1 doesn't exist anymore, and we're not seeing this in 33.0a1 or 32.0a2, it's probably not worth worrying about.
Fwiw, there's now one crash in 32.0a2: bp-c254d80e-215f-417d-a532-8c33c2140714
(still zero in 33.0a1)
