[BioC] biomaRt does not like flies

[Simon Anders]

Hi,

I'm trying to access Ensembl's D. melanogaster dataset via biomaRt.

This here works fine:

mart <- useMart( "ensembl", dataset="hsapiens_gene_ensembl" )

This command here, however, causes the R process to hang:

mart <- useMart( "ensembl", dataset="dmelanogaster_gene_ensembl" )

If I use Ensembl's web interface to Biomart, I can access both datasets 
just fine.

Any idea what the reason might be, and how I could find out whether the 
fault is local or on the web server? Is there any way to let biomaRt be 
a bit more verbose with diagnostic messages?

Cheers
   Simon
