For a few months Thunderbird crashes on Mac were reporting to our crash-stats server, but unfortunately weren’t being processed correctly.

Just before Christmas, Ted checked in a change to mozilla-1.9.1 to allow crash symbols to be generated via drawf-2 rather than the old method. Philippe then fixed up our Thunderbird tinderboxes. As a result, this work has fixed our crash-stats reporting and we are now getting valid reports at our crash-stats server :-)
