For whatever reason, whenever I try to launch Google Chrome via the KDE Start menu, I get this error:
KDEInit could not launch '/usr/bin/google-chrome-beta'
The thing is, I don't have google-chrome-beta ... I only have google-chrome, which I can launch from a shell window.
Q: How can I convince the KDE Start Menu that I only want to launch google-chrome instead of google-chrome-beta?
If I then right-click my running Google Chrome in the taskbar, and select "Show a Launcher When Not Running" and quit Google Chrome, I get a launcher that links to google-chrome-beta.
Q: How can I edit and fix a broken launcher?
One day I managed to fix things: The KDE menu was launching google-chrome correctly. I forget how I made that happen. Shortly after that, my Google Chrome launcher changed into a Chrome Web Store Payments launcher, which neither manages to launch anything nor, for the life of me, can I figure out how to remove it, so I have this dumb broken launcher icon stuck permanently to my KDE.
