[ROOT] TFile and IsOpen()

Hi,

In the following 3 line program, I would expect that IsOpen will return
false since the TFile pointer doesn't point to anything. Instead, I get a
segmantation fault. This happens with both v3.04-02 and v3.03-09. 

#include <TFile.h>
main() 
{
  TFile* f;
  f -> IsOpen();
  return 0;
}


I don't think I should get a segmentation violation here. There are a few 
cases where f -> IsOpen() returning false would be very useful. I was
wondering if this behavior could be implemented. 

Chhers,
