Review request for KDE Frameworks and David Faure.


Bugs: 338755
    https://bugs.kde.org/show_bug.cgi?id=338755


Repository: kio


Description
-------

kdesu is installed in libexec/ look for it there first. I left the findExecutable search as a backup.
Is looking in CMAKE_INSTALL_FULL_LIBEXECDIR correct? Or will kde-cli-tools be installed in libexec/kf5?

Insert 'kdesu' at the end to show a nicer error. If we leave this part out the error is "Could not launch 'root'" which is somewhat correct but not as easy to figure out as "Could not launch 'kdesu'"

Also added an unrelated QFile::decodeName() call.


Diffs
-----

  src/core/config-kiocore.h.cmake 3c2e4a8 
  src/core/desktopexecparser.cpp 9510697 

Diff: https://git.reviewboard.kde.org/r/120185/diff/


Testing
-------

Created .desktop file with X-KDE-SubstituteUID=true
Now I can launch it as root and when I remove kdesu I got a normal error message.


Thanks,

Maarten De Meyer
