This came after Andreas and Blake pushed some wrapper changes in bug 604363 and bug 604361 (from the set of checkins that went into the Oct 15 nightly: http://hg.mozilla.org/mozilla-central/pushloghtml?startdate=2010-10-14&enddate=2010-10-15 )

Only 3 crashes in the last 4 weeks and they were all old builds. Closing as fixed, feel free to choose a different resolution if desired.
