WARNING: DecodingException in block of code DIRECTIVES, length 35, file offset
45, block offset 18: unknown directive LAST
(IProfilerEventHandler`8 handler) [0x00000]
Original stack trace:

Unhandled Exception: System.NullReferenceException: Object reference not set to
an instance of an object
  at Mono.Profiler.ConsoleDecoder.Main (System.String[] argv) [0x00000]

Reproducible: Always

Steps to Reproduce:
The mprof file is 20 gigs so I will not be uploading it :).  One warning
occured during the run of my application.  Otherwise, it ran through to the
end.  When finished, it took a while probably writing the file, but no errors.

The error occurs when trying to decode.  The file was created using 
mono --profile=logging:c,a,o=out.mprof Myapp.exe

The warning was
*** nss-shared-helper: Shared database disabled (set NSS_USE_SHARED_DB to
My app does not use NSS (though I would love it if it did).

In case the decoder versions separately from mono, it would be good to add a
--version option.  Sorry, I am too lazy to file a separate bug on that.
