Import lexisnexis output into R quanteda

I would to use Benoit's R-package quanteda to analyze articles exported from lexisnexis. The export is in the standard html-format. I use the tm package + plugin to read the lexisnexis output. Unfortunately, an error occurs when transforming the tm-corpus to quanteda-corpus. Is that function broken, or is there something I get wrong before?

library("tm")
library("tm.plugin.lexisnexis")
library("quanteda")

ln <- LexisNexisSource("lexisnexisOutput.html")
cr <- Corpus(ln)
crp <- corpus(cr)

Error in UseMethod("corpus") : 
  no applicable method for 'corpus' applied to an object of class "list"
In addition: Warning message:
In corpus(texts, docvars = metad, source = paste("Converted from tm VCorpus '",  :
  Arguments docvarssource not used.

This was a limitation of corpus.VCorpus() when the texts were a vector of char types, not just a single char type. Fixed in quanteda 0.9.1-6. See Issue #80 on GitHub.
