Getting a core dump depends on your shell...

ulimit -c unlimited

...for bash.

As of now you can also build a trace enabled version of PyQt (build it with 
the -r flag). To switch traces on, put the following in your script...

# The SIP v4 module is called sip.
import libsip as sip

sip.settracemask(0xff)

...you can change the mask at any time. See the SIP_TRACE_* values in sip.h to 
see the detail of which trace messages correspond to which bit of the mask.
