创建声子媒体对象时出现分段错误

Question

我有使用PySide制作的音乐播放程序，该程序使用Phonon来播放音频。几天前我更新了MacOS X Mavericks，这意味着我需要重新安装PySide。我不确定这些操作中的哪一个导致了这种情况，但现在每当我尝试创建一个Phonon MediaObject时，我都会得到一个来自Python的分割错误：11。

它不仅在我的程序中，而且在尝试在Python中创建MediaObject而不执行任何其他操作时会发生。每当Mac崩溃时，我都会收到以下错误消息：

有人对正在发生的事情有任何想法吗？

Answer 1

从Qt 4.8.0升级到Qt 4.8.5似乎已经解决了这个问题。
