Description john haddon 2011-06-18 22:52:31 EEST

The code below reliably segfaults every time, with a long stack trace starting
with QCoreApplicationPrivate::sendThroughObjectEventFilters. The same code
works fine with PyQt4.

-------------------------------------------------------------------------------

from PySide import QtGui
from PySide import QtCore

class EventFilter( QtCore.QObject ) :

    def __init__( self ) :

        QtCore.QObject.__init__( self )

    def eventFilter( self, qObject, qEvent ) :

        return False

app = QtGui.QApplication( [] )

eventFilter = EventFilter()

widget = QtGui.QWidget()
widget.installEventFilter( eventFilter )

del widget

Works for me, no segfaults or errors at exit.

Comment 2 Luciano Wolf 2011-06-20 20:48:18 EEST

No problems so far. Everything works as expected.

Comment 3 Evan Patterson 2011-06-21 22:48:19 EEST

I've been getting intermittent segfaults related to eventFilter, so I did a
quick Bugzilla search and this came up. Sure enough, this reliably produces a
segfault on OS X using PySide 1.0.3.

I have not tested this on Linux yet.

Comment 4 Hugo Parente Lima 2011-06-21 23:49:15 EEST

This bug may be related to bug 892.

Comment 5 Hugo Parente Lima 2011-06-23 00:12:57 EEST

If possible, could you test it again using the latest version from git? Because
I think this issue could be solved by the commits used to fix bug 892.

Comment 6 john haddon 2011-06-23 10:16:49 EEST

Thanks! Building from the git version appears to fix it...

Comment 7 Hugo Parente Lima 2011-06-27 19:53:14 EEST

Thanks =], so I'll mark it as duplicated.
