最近我开始使用 Manjaro 18.0。除了 KDevelop 和 VLC 启动时崩溃外，一切都正常。
我的桌面环境是最新版的Deepin DE，之前也试过Budgie和Xfce，但结果都一样。
我的 VLC 版本是 3.0.4-6，KDevelop 版本是 5.3.0-1。所有应用程序都已升级到最新版本。

有没有什么解决方案或想法可以解决这个问题？提前谢谢！
更新：看起来这两个应用程序可以在 root 权限下（使用 sudo）运行。因此它可能存在权限和/或环境变量方面的问题。
答案1
好吧，现在我找到了一个解决方法。看来我使用的 Paprius 图标主题与这两个应用程序存在兼容性问题。现在我切换到 Deepin DE 的默认图标主题，它们都可以正常工作。
我稍后会向 Paprius 报告这个错误。
更新：Paprius 说这可能是 librsvg 的问题。我还向 GNOME 主题发送了一个错误报告。
