I don't know if this intro is of any relevance but I just plugged in my phone and was asked as usual whether I'd like to start Banshee. I wanted and so its main window popped up. As I noticed some moments later, it must have been during this procedure that a second Banshee icon was created (as last entry) in the Launcher.
Now, the second entry works as usually unlike the first one which changes its behavior almost every time I click on it. These are the different behaviors I could observe so far:
#1 Clicking results in it blinking as if I Banshee was starting up. This simply stops some moments later without any further reaction.
#2 Clicking results in the Banshee window popping up. Sometimes this happens in combination with #1.
#3 Clicking results in the second entry button doing some "dancing" / vibrating and flashing like in case of notifications. Similarly, it is then highlighted by a blue arrow on the left side afterwards and the Ubuntu button's top left corner becomes blue (see screenshot).
Other things to notice:
- The volume button's popup menu in the menu panel shows that Banshee is running. When I click on "Banshee", it reacts as described under #3.
- In the first button's right-click menu there's no "close" entry. In the second button's one the "Keep in Launcher" option is NOT checked as it should be.
*UPDATE*: I just clicked on the second entry and a *3rd* entry was created. Hiding and opening the Launcher again made the second button disappear. Now, the 3rd one behaves like the 2nd one previously.
*UPDATE2*: Can confirm the same bug for the calculator and GIMP now, so it seems to be of general nature. In these cases however, the first entry immediately disappeared. (I didn't even need to hide and open the Launcher again.)
Could you check if you have any desktop files related to banshee, in the .local/
