Description Alex Bikadorov 2016-10-21 18:16:50 UTC

My application is called "main_EXE", the config file is saved at "~/.config/main_EXErc" and this is the content:
>>>
[Startup]
MenuBar=Enabled

<<<

The (complete) application code:
>>>
#include <QApplication>

#include <KConfigCore/KConfigGroup>
#include <KConfigCore/KSharedConfig>
#include <KXmlGui/KXmlGuiWindow>

class MainWindow : public KXmlGuiWindow {
  Q_OBJECT

public:
  MainWindow() : KXmlGuiWindow(0) {

    KSharedConfig::openConfig()->deleteGroup("Startup");
  }
};

int main(int argc, char *argv[]) {
  QApplication app(argc, argv);

  MainWindow *window = new MainWindow();
  window->show();

  return app.exec();
}

#include "main.moc"
<<<

After running the code, this is the new content of the config file:
>>>
[Startup]
MenuBar[$d]

<<<

* removing the entry directly ( deleteEntry("ActiveTab") ) does not work too
* a sync() call writes the incorrect config to the file
* it works correctly if the config path is specified with a custom path
* it works correctly if the group was not in the config file when the application started (create+delete works)

And most important: When I search for "[$d]" in ~/.config/* , there are 10 config files with these invalid entries (ksmserverrc, oktetarc, khotkeyrc, plasmashellrc, ...). This bug is slowly messing up the config files for all KDE applications and can trigger further bugs.


Reproducible: Always
