I'm happy to report I have seen no more crashes. I'd appreciate a 4.13.2
release, so I have to deal with fewer calibre randomnly crashing bug reports.

Backout that change and apply the second one.
Doing that results in a crash, with the assertion causing the output
python2: objmap.c:267: add_object: Assertion `sw-flags 0x0200 == 0' failed.
Backtrace attached.

I was able to trace the python code that is triggering the assert.
Basically, it is the following sequence:
view = self.parent()
At this point view is a subclass of QMainWindow and view.parent() returns None
Calling view.size() causes the assert to be triggered. Interestingly the assert

hg pull -u
Done, albeit with hg clone -b 4.13-maint instead as pull wasn't doing the right
thing.
I'll let you know in a week if there are no more

OK, done. You'll hear from me in a week if there are no

I was unable to do this.
It's been a week and I have had no crashes since reverting sip to revision
1027. While that is by no means conclusive proof of a bug, it is highly
suggestive. Is there some extra instrumentation I can add to SIP to narrow down
the cause?

Hi all,
I've recently started getting random segfaults in calibre on my dev machine
(linux 64bit sip-4.13.1 and PyQt4-4.9). I compiled everything with -ggdb and
generated the following backtrace from a core dump (Only kept the top 15 calls)
#0 removeFromParent (self=0x5f66cc0) at siplib.c:5265

When Python desides to delete a Qt object from a different
