+Hello while trying to build propellor on jessie, I got this error message

+ picca@irdrx1:~/.propellor$ propellor
+ Preprocessing executable 'propellor-config' for propellor-4.9.0...

+ src/Propellor/Property/PropellorRepo.hs:17:37:
+ No instance for (Typeable OriginUrl) arising from a use of `toInfo'

+ In the expression:
+ setInfoProperty p (toInfo (InfoVal (OriginUrl u)))
