[ROOT] Segfault on ~TVirtualPS

Hi,

using root-4.00.03 and 04, compiled with gcc-3.3 or gcc-2.95
I get a fatal error after saving a postscript file, the moment
when TPostScript is being destroyed. To reproduce:

TF1 f("sin(x)","sin(x)");
f.Draw();
MENU: File -> Save As -> c1.ps

or...

TPostScript *ps = new TPostScript("test.ps")
TF1 f("sin(x)","sin(x)");
f.Draw();
delete ps;

This is on Linux/x86, debian-woody.

	Chris
