Since the code hasn't any apparent deficits, I would correlate your 
issues with your _ancient_ setup. A gdb backtrace with a proper debug 
symbols setup would sched some light onto the issue (palaeoanthropic  
wise), but I would update Qt, sip and PyQt at least.

For what is worth, with this setup all is fine:
python: 2.6
sip: 4.12-snapshot-1d6ba419952c
qt4: 4.7.1
pyqt4: snapshot-4.8.2-f509333f6b01
