It's not possible to pipe output of fetch to a file or a pager

fetch -i mallard | less -R

OSError: [Errno 25] Inappropriate ioctl for device

In fetch/info.py I changed

width,height = os.get_terminal_size()

to

try:
    width,height = os.get_terminal_size()
except OSError:
    width = 120
    height = 80

to get it to work

Thanks for reporting the issue. I have used your quick fix for OSError and will look deep in the issue for some better fix.
