[BioPython] Problem to open PDBid 2mbw

[Ismail Ekoprayitno Rozi]

Hi,
I'm not so good in python and I'd like to use Bio.PDB (fromp biopython 1.41) in
my scripts.
When trying to open PDBid 2mbw, the error bellow is coming out (other PDBid
seems to be opened normally).
Any idea how to solve it?

Thanks for your help,
I. E. Rozi
