Hi, 
is anybody else also running into issues when using mftparser on Win7 64 Bit?

I get the following:

WARNING : volatility.obj      : Cant find object NullString in profile <volatility.plugins.overlays.windows.win7.Win7SP1x64 object at 0xb4fc44c>?

Which results in entries like:

(FN) 0x184000|None\None\None\None\None\None\None|153380|---a-----------|0|0|480|1336379877|1336379877|1336379877|1336379877

Thanks,
Markus
