我最近开始遇到一个问题，当我搜索时，KRunner 会崩溃，但只有在输入第三个字符后才会崩溃。我可以毫无问题地输入、删除和重新输入最多 2 个字符。一旦我输入第三个字符，我就会收到崩溃通知。我在 Manjaro Linux 上使用 Plasma 5 桌面版本 5.3.1。
当我直接从命令行运行它时，我会在运行时得到以下输出：

我尝试禁用所有插件，这似乎可以防止任何崩溃，但我无法确定哪个插件导致了问题。如果有人对如何修复此问题有建议，我将不胜感激，因为 KRunner 是我日常工作流程的重要组成部分。
答案1
因此，行为不当的插件结果是windowed widgets.一旦我在 Krunner 设置中禁用该插件，我就不再遇到任何崩溃。我还没有确定导致崩溃的插件是什么，但如果确定的话我会报告。
答案2
@G-Man：抱歉，无法在下面发表评论。代表必须超过 50 岁？哦
无论如何：我解决了我的问题。我将范围缩小到文件夹~/.local/share/baloo
当文件夹被删除/移动时，我可以搜索所有内容。当该文件夹存在时，它会在第二个字符处崩溃。也许你也有同样的问题。
答案3
就我而言，这似乎也是 baloo 索引的问题。重命名文件夹时，~/.local/share/balookrunner 再次正常工作。
