[BioC] Entity 'nbsp' not defined using biomaRt

[Affeldt Severine]

Dear list,

I am using biomaRt for a few months now, and I have recently encountered a problem while using the 'useMart' function.

----------------------------
Here is my code:

library("biomaRt")
mart = useMart("ensembl")

I get the following error messages:
