Hi. I've been digging into a bug for a few days, now. After upgrading from Debian Sarge to Etch, our python application crashes (SEGV) if we install an event filter. Attached is a minimal example of the problem.
The application doesn't crash when commenting out the installEventFilter, despite the fact it does nothing. Does any one has a cue? I suspect a problem in KHTML sending a signal to a deleted object. It could also be that the "void *data" of the QCustomEvent causes problems in sip that can't possibly convert its type... Or maybe I'm just doing something wrong that will look obvious to an expert ^^ (gdb) bt #0 0xb781a1fd in sipQLayoutItem::sizeHint () from /usr/lib/python2.4/site-packages/qt.so #1 0xb7307264 in sip_api_convert_from_void_ptr () from /usr/lib/python2.4/site-packages/sip.so #2 0xb7307470 in sip_api_convert_from_void_ptr () from /usr/lib/python2.4/site-packages/sip.so #3 0x0808b9f3 in PyType_GenericAlloc () #4 0x08089495 in PyTuple_Size () #5 0xb72ffbc8 in sip_api_free () from /usr/lib/python2.4/site-packages/sip.so #6 0xb75ce7f2 in sipVH_qt_177 () from /usr/lib/python2.4/site-packages/qt.so #7 0xb787cb70 in sipQObject::eventFilter () from /usr/lib/python2.4/site-packages/qt.so #8 0xb6db4a18 in QApplication::internalNotify (this=0x82ade78, receiver=0x82eb258, e=0xbfc20594) at kernel/qapplication.cpp:2568 #9 0xb6db6a43 in QApplication::notify (this=0x82ade78, receiver=0x82eb258, e=0xbfc20594) at kernel/qapplication.cpp:2358 #10 0xb647ae0e in KApplication::notify (this=0x82ade78, receiver=0x82eb258, event=0xbfc20594) at /tmp/buildd/kdelibs-3.5.5a.dfsg.1/./kdecore/kapplication.cpp:550 #11 0xb65fa0cf in sipKApplication::notify () from /usr/lib/python2.4/site-packages/kdecore.so #12 0x082ade78 in ??
