[PyQt] [SIP][PATCH]Errors occurring during execution of python __dtor__() function called from sip are discarded

[Alexis Boutillier]

Hi,

When sip call the __dtor__() python function on a python object, it does 
not print errors that occurred during the execution of the python function.
If something goes wrong in this function you are not informed and so you 
can leave objects in an unwanted state (because of an attributeError for 
example).

Here is a patch to siplib.c that print the python error if it occurred 
during the call of the python "__dtor__()" function.
Patch is against sip-4.8-snapshot-20090401
