To reproduce the bug:

• create a corpus with that file: https://dl.gargantext.org/GarganText_DataPhyloBug.zip
• generate a phylo with default parameters
• when the phylo is generated (no more space bar), click on the Phylo node

In the backend you get this error: ##########################

-- | Phylo with level = 0.8 applied to 276 foundations

-- | Export 22 branches, 172 groups and 89 terms

-- | Convert 3 branches and 153 groups 89 terms to a dot file
