Since Dirk made me look into it (in spite of himself :), here's how to print 
the contents of a QString in gdb. Very easy, in fact.

Put this in your ~/.gdbinit :

define printqstring
       set $i=0
       while $i < $arg0.d->len
         p $arg0.d->unicode[$i++].cl
       end
end

Then in gdb you can do
printqstring myqstring
to see its contents.

For instance, 
QString myqstring = QString::fromLatin1("contents"); 
can be examined using
(gdb) printqstring myqstring
$1 = 99 'c'
$2 = 111 'o'
$3 = 110 'n'
$4 = 116 't'
$5 = 101 'e'
$6 = 110 'n'
$7 = 116 't'
$8 = 115 's'

Quite handy :)

BTW: gdb 4.1x sucks, gdb 5.x rocks. You know which one you want to use :)
