To reproduce the error:
$ wget http://dbnsfp.houstonbioinformatics.org/dbNSFPzip/dbNSFP2.0.zip
$ python Python 2.7.4 (default, Sep 26 2013, 03:20:26) [GCC 4.7.3] on linux2 Type "help", "copyright", "credits" or "license" for more information.
from zipfile import ZipFile
with ZipFile("dbNSFP2.0.zip", "r") as zf: ... with zf.open("dbNSFP2.0_variant.chr20", "U") as f: ... count = 0 ... for line in f: ... count += 1 ...
print count 964352
$ unzip -p dbNSFP2.0.zip dbNSFP2.0_variant.chr20 | wc -l 2161277
may it be related to issue 6759 ?

Could you please test with in-development version Python 2.7.6+? Unlikely it is related to , but perhaps it is related to .

With 2.7.6+ works fine.

I tested it with Python 3.3 and works fine too.
