Formatting lost on io.js

[binarykitchen]

On io.js with longjohn, I see this output in my app:

Console.trace (console.js:80:17),/home/michael-heuberger/binarykitchen/code/videomail.io/src/server.js:130:25,LevelUP.<anonymous> (/home/michael-heuberger/binarykitchen/code/videomail.io/src/db/level/driver.js:29:23),emitNone (events.js:67:13),LevelUP.emit (events.js:163:7),/home/michael-heuberger/binarykitchen/code/videomail.io/node_modules/level/node_modules/level-packager/node_modules/levelup/lib/levelup.js:122:12

Line breaks are lost, gone.

Whenever I comment out longjohn, then all is formatted nicely:
