When running konsole(KDE 3) I get a crash, I traced it to the following 
code:

void Konsole::setFont(int fontno)
{
  QFont f;

  QFontMetrics fm1(f);
  int font_w;

  font_w = fm1.maxWidth();
  cout << "font_w31:" <<font_w << "\n"; // This returns 12

  if (fontno == DEFAULTFONT)
    f = defaultFont;
  else
  if (fonts[fontno][0] == '-')
    f.setRawName( fonts[fontno] );
  else
  {
    f.setFamily(fonts[fontno]);
    f.setRawMode( TRUE );
  }

  QFontMetrics fm2(f);
  font_w = fm2.maxWidth();
  cout << "font_w32:" <<font_w << "\n"; // This returns 0 (Not good )


***************** End of relevent code ***************
The debugger shows:

p fonts
$2 = {0x808b9c0 "6x13", 0x808b9c5 "5x7", 0x808b9c9 "6x10", 0x808b9ce 
"7x13",
  0x808b9d3 "9x15", 0x808b9d8 "10x20",
  0x808b9e0 "-misc-console-medium-r-normal--16-160-72-72-c-160-iso10646-1",
  0x808ba20 "-misc-fixed-medium-r-normal--15-140-75-75-c-90-iso10646-1"}

So the code goes through :
     f.setFamily(fonts[fontno]);
     f.setRawMode( TRUE );

with fontno = 3  fonts[fontno]="7x13"

 From the QT manual:

Warning: Do not use raw mode unless you really, really need it! In most
 (if not all) cases, setRawName() is a much better choise.

However setRawName requires an XLFD , and "7x13" is not an XLFD so
this does not work.
Any ideas?

P.S I do have Hebrew as a second language on this system
