OS 12.2, 3.4.11 kernel on x86_64, KDE 4.9

Simple question, really, but I was wondering if there was a more meaningful underlying cause to this issue.

I can't add LibreOffice apps to the quicklaunch. If I choose "Show a Launcher When Not Running" from the application's taskbar context menu, an icon will indeed show up. However, after closing the application, when I click on the newly placed LibreOffice icon, I get an "Open with..." dialogue asking me which program to use to open soffice.bin, regardless of which LibreOffice application has been placed there, or how long or after how many reboots it's been placed there.

So, exactly how does one add a useful LibreOffice icon to the quicklaunch?
