PySide6 6.8.0在Linux下给QWebEngineView装事件过滤器触发段错误

在Linux系统的PySide6 6.8.0版本中，运行以下代码会触发段错误（segmentation fault）：

import sys
from PySide6.QtCore import QObject, QUrl
from PySide6.QtWidgets import QApplication, QWidget
from PySide6.QtWebEngineWidgets import QWebEngineView


class Obj(QObject):
    def eventFilter(self, obj, e):
        print(e)
        return False

app = QApplication(sys.argv)
#w = QWidget()
w = QWebEngineView()
w.setUrl(QUrl('about:blank'))
obj = Obj()
app.installEventFilter(obj)
w.show()
app.exec()

问题说明 #

该问题仅在使用QWebEngineView时出现，替换为普通QWidget则无异常。

若将事件过滤器安装到具体的QWidget实例而非全局QApplication上，程序可正常运行，示例代码如下：

import sys
from PySide6.QtCore import QObject, QUrl
from PySide6.QtWidgets import QApplication, QWidget
from PySide6.QtWebEngineWidgets import QWebEngineView


class Obj(QObject):
    def eventFilter(self, obj, e):
        print(e)
        return False

app = QApplication(sys.argv)
wid = QWidget()
wid.show()

w = QWebEngineView()
w.setUrl(QUrl('about:blank'))
obj = Obj()
wid.installEventFilter(obj)
w.show()
app.exec()
