KDE's systemsettings.desktop contains an invalid argument in Exec=

[TK]

The files systemsettings.desktop and kdesystemsettings.desktop contain the line:
Exec=systemsettings -caption "%c" %i

Executing this command results in:
systemsettings: Unexpected argument '%i'.

I should add that as the systemsettings.desktop entry is embedded within the XFCE xfce4-settings GUI, it does not execute because of this error. This leaves XFCE users no way ot execute the KDE systemsettings from within the XFCE menus

Both %c and %i are valid field codes as per [1]. Throwing at libxfce4menu, hoping it has something to do with desktop file processing :S

I agree, I incorrectly titled this bug.

To elaborate a bit, the problem is not in the entry file nor in the XFCE menus. When logging into a pure XFCE environment, the systemsettings.desktop works correctly from within the XFCE menus.

The problem is when logging into the Xubuntu environment. The "KDE system settings" are not displayed in the application menus, rather they are embedded within the xfce4-settings graphical user interface (see attached window capture, bottom left).

When attempting to run the program from within this window, xfce4-settings cannot correctly process the switches within the entry file. The %i prevents execution, the %c displays in the title bar as literally "%c".

clicking on corresponding icon gives nothing.
The reason is printed into console:
systemsettings: Unexpected argument '%i'.
systemsettings: Use --help to get a list of available command line options.

systemsettings works just fine when executed manually, so xfce4-settings should call it with correct options. Also if call fails for whatever reason user should be presented with error message in gui instead of silent failure.

Status changed to 'Confirmed' because the bug affects multiple users.

[Simon Steinbeiß (ochosi)]

This is not a bug in xfce4-settings, as it doesn't add parameters to the calls itself. Rather this would have to be fixed in systemsettings' .desktop file.

Reassigning to systemsettings per upstream Xfce discussion.
