this script causes a segfault for me with latest SIP snapshot and PyQt

Is this a recent problem with current snapshots?
This specific testcase crashes also with older versions of SIP and PyQt
(4.4 and 3.16).
I'm getting a serie of crashes, all related to QApplication destruction
and event delivery, which never triggered before but now trigger with
recent SIP snapshots. This is the first testcase reduction I made (they
are pretty difficult to reduce!). I have probably at least another to
report that I'm still reducing.
Is there a real use case (you'd never actually code the above)? Otherwise just
remove the "del".
Yes, the real use case is an automatic testsuite. For each test, I need
to create and destroy a new QApplication to start afresh. It kind of
works in C++, but I have historically always had troubles with PyQt. A
generic workaround for me right now is to put a qApp.processEvents()
before app destruction, but I would prefer if the bugs were fixed (and I
thought you preferred it too...).
