Attaching sample reader and baddata.bin.

Expected:
tedu at ted-vm1:/tmp$ ~/mono/2.0/bin/mono readbad.exe readbad.cs
read them all

Or even reading itself, a fairly nonsensical string:
tedu at ted-vm1:/tmp$ ~/mono/2.0/bin/mono readbad.exe readbad.exe
read them all

With attached file:
tedu at ted-vm1:/tmp$ ~/mono/2.0/bin/mono readbad.exe baddata.bin
