You can at least show the actual line that fails. Are you trying to open 
a file, a named socket, a pipe or a device?

The first two google hits for "bad file descriptor" seem pretty relevant 
to me:

Possible, but you should get 

Errno 2 No such file or directory 

not bad file descriptor.

If you're trying to open a file, you have a broken file system and need 
to run fsck or equivalent. If it's a pipe or socket or something, you 
need to tell us what it is.
