The problem that was preventing makeTranscriptDbFromBiomart() to
fetch the 'chrominfo' data frame (i.e. chromosome lengths) from
Ensembl has been fixed. Make sure you update to the latest version
of GenomicFeatures (v 1.6.5 in BioC release, v 1.7.8 in BioC
devel). Available via biocLite().

The warnings about duplicated levels still need to be investigated.

Cheers,
H.
