Comment 1 Allen Winter 2012-01-30 17:00:25 UTC
looks like a but in Qt's implementation of QUuid.  where maybe they don't detect certain failure conditions with /dev/urandom.

all we are doing is calling the static function  QUuid::createUuid() and that should not crash.  so I'm blaming qt for the moment.
