Check out the spoon package on hackage. It's designed for these kinds of situations, and will wrap up common user-generated "pure" exceptions into a Maybe (and will return Nothing in the cases you describe)

Hi, cafe,

I'm working in a program where I use many connections with Network.HTTP.
Sometimes, connections are closed while my program is reading them, and an
error appears:

<socket: XXX>: Data.ByteString.hGetLine: invalid argument (Bad file
descriptor)

All I need is to handle this error. The function 'catch' doesn't work. I
guess this error comes from a call to 'error' function, or something
similar.

What I can do?

Thanks in advance,
Daniel Díaz
