[ROOT] calling constructor 0x0???

Dear rooter,
Please look at the following output of root:
-----------------------
root [] .trace
trace all source code
root [] .x raw_spectra.C
//
2
3    {
4      gROOT->Reset();
5
......
9      TFile *fqfs = new TFile("qfs.root","update");
!!!Calling constructor 0x0.TFile for new TFile
......
32     TFile *fmon = new TFile("monitor.root","update");
!!!Calling constructor 0x0.TFile for new TFile
......
----------------------
I'm quite sure that all the files exist. Why did root warn me like that? 
When I switch on trace and execute command such as "TFile *f = new 
TFile(...)",  I get this warning. I don't understand.

Regards.

Exaos
