I have a new upgrade to 11.4 running KDE 4.6.1 from the KDE46/11.4 repo.
I added the k9copy application from packman.
It is loaded and runs.
On my desktop, I dragged the k9copy.desktop file onto the"Desktop Folder" (I made a copy) from /usr/share/applications.
When I open the Desktop Folder in Dolphin, detailed view, see the correct ikon to the left of k9copy.
But on the desktop, the Desktop Folder shows a default (rectangle with curled right corner) ikon.
Interestingly, when I click on the ikon to start k9copy, the correct ikon shows briefly, then the application window opens
I have tried right click-Refresh View
