Kde environment becomes unresponsive after launching Digikam appimage

[Maik Qualmann]

Hi Marc,

I don't know what the AppImageLauncher does and works exactly. However, we had 
to remove the call to KService in the AppImage and replace it with something 
of our own. KService creates and manages KDE's Mime database to connect mime 
types to applications. When we tried to get an application (Open With...) to a 
mime type, digiKam completely froze and KService ran in circles.

The problem only occurred when the desktop was running a relatively current 
KF5 version.
