We've removed Bio.FormatIO for Biopython 1.44 (in favour of Bio.SeqIO).
It was a input/output framework based on Martel "regular expressions" to 
describe file formats.

I think it was an innocent looking "from Bio import GenBank", which I 
have never seen cause this error before. Hence my wondering if there was 
an installation problem (e.g. a partial installation).

I think Bio.formats and the registry thing are all tied together with 
code in Bio/formatdefs,  Bio/config etc.  Its all very complicated, and 
doesn't seem to be much documented.
