I can't reproduce it even with -03 -march=athlon. I'm really suspicious of the 
backtrace. The relevant line is

Q_ASSERT( filter != NULL );

Q_ASSERT is #defined as:

#if !defined(Q_ASSERT)
#  if defined(QT_CHECK_STATE)
#    if defined(QT_FATAL_ASSERT)
#      define Q_ASSERT(x)  ((x) ? (void)0 : qFatal("ASSERT: \"%s\" in %s 
(%d)",#x,__FILE__,__LINE__))
#    else
#      define Q_ASSERT(x)  ((x) ? (void)0 : qWarning("ASSERT: \"%s\" in %s 
(%d)",#x,__FILE__,__LINE__))
#    endif
#  else
#    define Q_ASSERT(x)
#  endif
#endif

Do you have QT_FATAL_ASSERT defined? Do you get the assertion message before 
the crash? You tried a fresh build, right? Anyone else have this problem?

Valgrind?
