【问题描述】：

我正在尝试将 Web 浏览器嵌入到 gtk 项目中。我正在尝试使用 WebKitGTK（但我不致力于它），每次我尝试使用它来解析 Ext JS 页面时，它都会使整个应用程序崩溃。这是输出，以及我如何包含 .js 文件...

.js 文件...

任何建议都会很棒，这真的是我剩下的唯一障碍。谢谢！

【问题讨论】：

（我在你的另一个线程上发布了这个，为了完整起见，我会重复一遍），对不起，我在美国东海岸，目前没有电。我的上网时间有限。从我看到的你的错误来看，它们来自 nspluginwrapper，你是嵌入 flash 还是什么？

还有一件事，“崩溃”是什么意思？你能得到一个堆栈跟踪吗？

感谢您的回复。原来这是一个Ubuntu问题。我在他们的错误跟踪网站上发布了带有堆栈跟踪的错误报告。所以是的，我有一个带有堆栈跟踪的核心转储。我仍然无法查看几个 Ext JS 页面，但我认为这只是一个 webkit 问题。再次感谢您的支持，祝您好运。

【参考方案1】：

这是我使用的 flash 插件的 Ubuntu 问题。这是堆栈跟踪。

【讨论】：

你在哪里找到那个堆栈跟踪...你是怎么解决这个问题的？

对不起，如果还不算太晚，这是一个 gdb 跟踪。我相信我刚刚卸载了 flash 插件。
