SUMMARY
In the "Places" menu of the application launcher, the "Computer" submenu has a "Show KRunner" button at the top. It's possible to make this button's appearance (but not its behavior) change entirely by fiddling with the UI - this will make the button look like it's going to open a folder on the system, when in fact it still will show KRunner when clicked.

NOTICE! This bug is not 100% reproducible. However, it happens frequently enough when trying to reproduce it that it should be easy to reproduce.

STEPS TO REPRODUCE
1. Click on the Application Menu.
2. Click the "Places" tab at the bottom. The topmost button should say "Show KRunner".
3. Mouse over the "History" submenu.
4. Move the mouse into the history list, scroll all the way down, then scroll all the way up again.
5. Mouse over the "Computer" submenu again.

OBSERVED RESULT
Some item from the History menu now appears to be the topmost button. Clicking this button will show KRunner.

EXPECTED RESULT
The button should always say "Show KRunner" and not take on the identity of any other button.
