当我在KDE的QT中打开项目时，我遇到了seg错误。 错误是：
QtCreator(20093)/ findLibraryInternal: plugins should not have a 'lib' prefix: "libkfilemodule.so"
QtCreator(20093)/ KPluginLoader::load: The plugin "libkfilemodule" doesn't contain a kde_plugin_verification_data structure
kdeinit4: Communication error with launcher. Exiting!

我也尝试过创建softlink：
ln -s libkfilemodule.so kfilemodule.so，但仍然遇到同样的问题。
答案 0 :(得分：0)
如果您遇到Qt 4.6并且无法升级到更新的一组库...
基本上最简单的解决方法是，如果您有权访问源代码，则停止使用QFileDialog调用。我用QInputDialog::getText替换了我的，现在没有更多的seg错误！
此错误报告也谈到了它：

希望有所帮助。
