convert_ensembl gives erratic results

[dputhier]

When checking checksum with md5, the result of convert_ensembl differs from one time to another:

  $ gtftk get_example | awk '$3 != "transcript"' | awk '$3 != "gene"' | gtftk convert_ensembl  | md5sum-lite | sed 's/ .*//'
  69d25cd2aa1fcb7afb426c853e2d63e1
  $ gtftk get_example | awk '$3 != "transcript"' | awk '$3 != "gene"' | gtftk convert_ensembl  | md5sum-lite | sed 's/ .*//'
  5dd54b496fae898908da36eae0fdd5f1
  $ gtftk get_example | awk '$3 != "transcript"' | awk '$3 != "gene"' | gtftk convert_ensembl  | md5sum-lite | sed 's/ .*//'
