当我打开 Linux 笔记本电脑时，系统提示 kdeinit5 已崩溃。这似乎没有影响，我可以正常使用 Firefox，并且 kde plasma 小部件和工具栏会像往常一样显示。我附上了两次启动的两组崩溃信息。

我打开电脑，两次被告知 kdeinit5 崩溃了，并且 Baloo 文件索引守护进程崩溃了。

总结：索引 Plasma Vaults 会导致问题。请从文件搜索中排除 Vaults 所安装的文件夹。
我在 reddit 上发布了这个问题，然后用户斯库格勒回复
看起来 kio 缩略图进程和 Baloo 进程正在崩溃，这可能意味着缩略图尚未创建，文件未被索引。这些事情并不致命，您在使用过程中可能根本没有注意到它们，或者您的索引器可能缺少文件的内容，导致无法生成某些缩略图。（来源）
我意识到问题开始于我创建等离子库。保管库是加密文件夹，存储在隐藏位置，解锁后会挂载到预先存在的空文件夹中。就我而言，我有一个名为“Secrets”的保管库，它挂载到空文件夹“~/Secrets”中。
索引错误和缩略图生成错误都与尝试索引 Vault 文件夹中消失的内容有关。在我将 Vault 安装到的目录添加到“系统设置”的“文件搜索”窗格中“文件搜索”未索引的目录列表后，我不再收到错误消息（如下图所示）。
