I am running ArchLinux and I have started firefox from the terminal. Then I go to the download manager to try to open my "file browser" by clicking on "open containing folder", but it does not open and I get this message in the terminal /usr/share/applications/kde4/dolphin.desktop: line 1: [Desktop: command not found /usr/share/applications/kde4/dolphin.desktop: line 8: be@latin: syntax error: invalid arithmetic operator (error token is "@latin") ... /usr/share/applications/kde4/dolphin.desktop: line 182: di: command not found /usr/share/applications/kde4/dolphin.desktop: line 183: Managerxx: command not found so it is clearing trying to open the "file browser" through a desktop entry, and fail, but the desktop entry "dolphin.desktop" works fine. so what is going wrong?
