I have a workaround for this bug.  It appears because cygwin throws an
IOError exception with num=0 when closing the /dev/urandom file.  The
workaround is to change line 120 in
/usr/lib/python2.5/site-packages/Crypto/Util/randpool.py to read:

                if num!=2 and num!=0 : raise IOError, (num, msg)

Using this workaround, bzr seems to function normally.

I've posted a bug report with this workaround at:
