panic: runtime error: invalid memory address or nil pointer dereference

[runarheggset]

I encountered a panic while encoding some documents. Unfortunately I can't provide the documents, as they are private.

After a quick look, it seems that pairEncoding in util.go:108 is nil, so the GetIds() call fails.
