Raul, did you maybe clear the needinfo by mistake? We're wondering if you can provide us with a profile of the issue (see comment #3 for information on how to produce a profile).

Hi Greg. Yes, I did it by mistake on all 4 mentioned reports that were moved. Nightly crashed whilst the tabs were opened. Will provide the info ASAP. Is it possible to re-add the needsinfo flag on the other 3?
