runebar error

[Caellian]

So i finally decided to try a DK, better late than never lol.

Using my good old layout i get this error (latest oUF version from wowi)

ID: 1
Error occured in: Global
Message:
...nterface\AddOns\caelUI\libs\oUF\elements\runebar.lua line 100:
   attempt to perform arithmetic on local 'start' (a nil value)
Debug:
   [C]: ?

locals:
(*temporary) = "RUNE_POWER_UPDATE"
(*temporary) = 1
(*temporary) = "RUNE_POWER_UPDATE"
(*temporary) = 1
(*temporary) = <function> defined =[C]:-1

Anyone has a clue where it comes from and how to fix it ?

On a side note, is oUF abandonned or something ? I know, if it's not broken, don't fix it but, it's been a while since haste updated it here or on his repository.
