I have a problem with my Fedora 24 installation:
On some specific UI Action, the gnome shell crashes. Two of the actions fail nearly every time: Closing the VLC player while it is playing a video and attemping to take a screen-selection with Shutter.
I am running Fedora on a notebook with the latest Intel graphic drivers provided by the distribution. The notebook has also an Nvidia graphics card and I was once running it on the proprietary Nvidia driver, but I uninstalled it because it hurt the battery too much. I think the driver might have left some garbage which causes the problems. (I uninstalled it via the official executable, though).
Here is a journalctl output just before such a crash: http://pastebin.ca/3720387
There are some errors, but I don't really know what they mean and Googling them does not give relevant information.
