Bug Description
I am burning a 14GB ISO to BD-RE media. The burn completes successfully, but brasero appears to crash every time at about 70%, or after about 9531MB. At this point the dialogue stops updating (see screenshot). When the burn finishes some time later, the dialogue indicates success and the disc ejects.
EDIT: The "can only burn once" problem is a different bug, already reported and not specific to large ISOs.

This bug happens because the growisofs plugin does not parse growisofs output properly. We have this line of code:
burn-growisofs.c: if (sscanf (line, "%10lld/%lld (%4d.%1d%%) @%2d.%1dx, remaining %*d:%*d",
The "%10lld" format specifier stops working when the number of bytes reaches 11 digits, which happens at about 9GB.
