(gdb) bt
#0  ~QIconSet (this=0x8209614) at qshared.h:50

~QIconSet (this=0x8209614) at qshared.h:50
50          bool deref()        { return !--count; }
(gdb) print this
$1 = (QIconSet * const) 0x8209614
(gdb) print *this
$2 = {_vptr.QIconSet = 0x41048ba8, d = 0x5}

It looks as if "d" was corrupted in toplevel.
