文件打开/保存对话框失败

  • 772

几个月前，我的 Ubuntu 20.04 出现了一个非常奇怪的问题，现在仍然存在。我尝试了很多方法来解决它，包括将操作系统升级到 24.04。都没有任何帮助 - 因此，我需要专家的帮助，这将不胜感激。当我调用文件打开或/和另存为对话框（例如，通过 ctrl+o）时，几个应用程序（但不是全部）崩溃/冻结。这些应用程序包括 Okular、Texstudio、Wolfram Mathematica。我用 GDB 进行了回溯 - 下面我附上了 Okular 的输出。直觉上，我猜这个问题与 GTK、FileChooser、Qt 及其库有关。但简单的重新安装并没有帮助。不要犹豫，询问任何细节。我使用 Gnome v46 和 X11。这个问题只与我的主要用户有关。也就是说，如果我通过 sudo 启动提到的应用程序，则不会出现这个问题。

    今天我突然解决了这个问题，这让我很高兴。想到 Qt，我进入了机器上的 ~/.config 目录，发现文件“QtProject.conf”处于奇怪的状态：它的大小约为 1 Gb (!) 并且被锁定了。只需删除此文件即可。一旦更新，上述应用程序的操作就恢复正常！就是这样的故事。
