Kees Cook and I discovered that something, either whoopsie or daisy or pycassa I guess, is replacing values that contain tabs with question marks. This error report contains ? instead of tabs in the Registers field:
https://errors.ubuntu.com/oops/e97b1abc-66bd-11e4-9406-fa163e525ba7
Registers:
rax 0xfffffffffffffdfc?-516
rbx 0x2782a60?41429600
rcx 0xffffffffffffffff?-1
rdx 0xb51?2897
rsi 0x3?3
This is also true in the database.

I've noticed this issue both from clients running 14.04 and 15.04. Other fields that include tabs are ProcStatus. |
