Hi Bow,

I've just updated the 64bit Linux buildslave from Python 2.7.3 to
2.7.4 and there
is a new unicode failure with the BLAST XML writing code in SearchIO (below).

Can you reproduce this? Keep in mind this could be a new bug in Python itself ;)

Separately the are some BGZF issues, see also this thread:
http://lists.open-bio.org/pipermail/biopython/2013-April/008490.html

Thanks,

Peter
