Sorry, logs took a while

Thanks. @ditman any ideas on this one?

[ditman]

/cc @mdebbar added a linkDelegate recently; he might not have had time to publish all the packages he's worked on.

Closing the loop here: Mouad published the fix for this one. Apologies for the breakage! /cc @dnfield @jonahwilliams
