When opening the Applications submenu in Kickoff first time after boot, it shows "Applications updated" notice shortly before you can access the menu. I assume that it shouldn't do this every time but I might be wrong. When I updated to Plasma 5 I removed some Wine related shortcuts (used to launch Windows programs installed using Wine) manually from some configuration folders. I don't know if this had any effect on the menu behavior but it's useful to know, I suppose. Reproducible: Always Steps to Reproduce: 1. Reboot the computer and log in. 2. Open the Kickoff menu. 3. Select Applications submenu/tab. Actual Results: The "Applications updated" notice is shown
This was rewritten for 5.5 so is hopefully fixed. Please reopen if not.
