Caja——MATE 桌面文件管理器——立即崩溃每次我打开任何包含一个或多个 JPG 或 PDF 的文件夹时。
一两秒之后文件夹就消失了——我甚至没有时间尝试打开 PDF 或 JPG。
我在跑Caja v.1.26.0-1ubuntu1在Ubuntu MATE 22.04 Jammy Jellyfish在桌面工作站上。
我目前所做的：
禁用了 Caja 的所有扩展并重新启动。没有帮助。
彻底删除了 Caja 及其相关程序，重新启动，重新安装 Caja 及其相关应用程序和库（逐个安装）。没有帮助。
确保所有文件和文件夹权限正确。
删除了所有未使用或不需要的与 Caja 相关的程序 - 我将所有与 Caja 相关的程序与我在 20.04 安装在单独的内部驱动器上的 caja 相关应用程序列表相同，Caja 在其中运行没有问题。
以下是当前安装的 (15) 个 Caja 应用程序：
caja、caja-admin、caja-common、caja-eiciel caja-extensons-common、caja-gtkhash、caja-mediainfo、caja-open-terminal、caja-rename、caja-seahorse、caja-sendto、gir1.2-caja-2.0、libcaja-extension1 python-caja-common python3-caja
我已经将这些全部删除并逐一添加回来。
有一次，由于我无法在 GUI 显示屏中打开 PDF 或 JPG，所以我从终端的命令行打开了一个 PDF。这导致我的桌面上的图标闪烁，直到我重新启动。我从未见过这样的闪烁，我想知道当这种情况发生时，这是否可能表明桌面上发生了什么具体的事情。
以下是我主目录中 .xsession-errors 文件中的一些相关行：

我们欢迎任何关于导致崩溃的原因的想法，无论它们有多么离奇。 谢谢。
答案1
解决了：
我进入文件管理器，打开“预览”选项卡，并将其中的所有内容设置为“从不”。
然后，我一个接一个地取消“从不”并重新设置为“始终”。
问题在于“其他可预览文件” -> “显示缩略图”环境。
如果设置为“从不”，问题消失了。
由于我不需要缩略图预览，我现在将“显示缩略图”设置为“从不”。
