我也遇到过此类问题，不过并不是每次都会这样

十有八九是bug...留一下backtrace吧
先装一下libdde-file-manager-dbgsym dde-file-manager-dbgsym gdb这几个包
关掉所有文件管理器窗口 开一个终端输入gdb dde-file-manager (回车) r (回车)
操作到文件管理器自动关闭 然后在终端输入 bt (回车)
然后把整个终端里的内容都贴上来吧

(gdb)

忘了说命令需要等到出'(gdb)'的提示符之后再输了。。。上面写的步骤里每一次按回车（包括最后一次）都可能要按许多次直到输出'(gdb)'之后再输后面的命令。
麻烦lz重做一遍再帖一次吧

呃……是我没看清楚

感觉有点玄学  看起来文件管理器是正常结束的。用gdb启动文管的时候可以复现bug吗？

用gdb打开文件管理器，点击色彩标注的文件夹，就卡住了……

就在这里卡住了

现在我已经解决问题了——取消原来的色彩标记，重新设定一个，问题就消失了……我也不知道到底发生了什么

我上面表达失误了……应该是操作到文件管理器卡住去终端里打bt，不是操作到退出。。。
不过问题解决了就好^^

好吧，不管怎么说，谢谢你的热心！
