kapacitord config command panics

[karel-rehor]

kapacitor.conf.txt
In cmd/kapacitord/main.go:132 it would appear that the command 'config' should print out a configuration to the console, as is the case with influxd and telegraf. However, when I try this on the latest nightly build, it panics as follows.

panic: unexpected reflect.Kind: func [recovered]

Console messages from latest attempts:

Note, that I first encountered this last week on a local build of 1.4-RC1.

Found where the issue is coming from, its the mqtt section. Going to investigate why specifically now.
