    Hi there.

    I found a problem in the error handling of a file open. When the
    CreateAttFile method of the Sanitizer.pm module opens a file using
    IO::File->new() -- there is no checking if the call actually succeeded.

    How do I know this? Cause I'm a silly bugger who had his /tmp directory
    accidentally set to mode 755 instead of 1777.

    Anyway. I'm not gonna make a big post about a small bug in an otherwise
    neat piece of software. I'm not much of a perl programmer, and didn't
    much get into looking at the code's convention of error handling. What
    I did do is conjure up this patch:

    diff -urN anomy/bin/Anomy/Sanitizer.pm anomy-henry/bin/Anomy/Sanitizer.pm

                (!defined ($fh = IO::File->new($$fn, O_CREAT|O_EXCL|O_RDWR))));

    + {
    + die "Can't open temporary file!";
    + }
         binmode($fh);
         return $fh;
     }

    Keep up the good work, guys.

    Kind regards,
    Henrý.
