问题描述

限时删除!!

自从Maverick升级以来,我的Qt应用程序出现了一个奇怪的问题当关闭简单的Qmessagebox或在QWebView上的javascript内执行alert()或Confirm()时发生事件时,它们都会崩溃.

Since upgrading on Maverick I have a strange issue on my Qt appsThey all crash when closing a simple Qmessagebox or event when doing alert() or confirm() inside javascript on a QWebView..

因此,即使 javascript 也使应用程序崩溃,我认为这不是错误的 C++ 代码?

So if even javascript makes the app crash, I assume this is not wrong c++ code ?

我不知道从哪里开始,该怎么做.我已经使用预先构建的Qt 5.2.0进行了编译,并且我自己编译了同样的结果...

I don't know where to start, what to try.I've compiled with the prebuilt Qt 5.2.0 and one I compiled myself with the same result...

这是Mac OSX上的崩溃日志:

有趣的是,我不知道这是否相关,但是...Qt Creatorr的行为方式相同.出现对话框(如首选项)并返回到主框架时,它崩溃.

The funny thing, I don't know if this is related but...Qt Creatorr behaves the same way. When having a dialog (like preferences) and getting back to the main frame, it crashes.

这与某种聚焦后背"有关吗?

Has this to do with some sort of 'back in focus' ?
