It crashes at 16H25 (local time paris) and a few minutes after (8) I see the same user doing task in background (they download data with a particular URL in BGtasks) with a Delay that is consistant with a background wait of 5 or 7 minutes.

I have no more information on this crash and by the way Xcode refuses to load it and shows an error. ( I did a report via Xcode for this).
