This doesn't matter for python 2 uses, but in python 3, you can get things like:

hdr['descrip'].item().split(';')
    ---------------------------------------------------------------------------
    TypeError                                 Traceback (most recent call last)
    <ipython-input-42-a30eaa7f7322> in <module>()
    ----> 1 hdr['descrip'].item().split(';')

    TypeError: 'str' does not support the buffer interface

It's possible to cast this object to a str, but that's a bit sketchy:

str(aa.item())

    "b'te=5.63;ti=0;fa=20;ec=0.0000;acq=[128,128];mt=0;rp=1.0;ves=0.859437;ve=50'"

One solution that works for me right now is to call:

hdr['descrip'].decode('utf-8')

on the resulting description field, but maybe this should be pushed into the creation of this field?
