Alternatetab Error: second argument to Lang.bind() must be a function, not undefined
The Tweaks application reports Error loading extension
for Alternatetab.
Using journalctl /usr/bin/gnome-shell
I was able to find:
Dec 07 17:22:33 foo gnome-shell[1456]: Extension "alternate-tab@gnome-shell-extensions.gcampax.github.com" had error: Error: second argument to Lang.bind() must be a function, not undefined
I upgraded the extension and also uninstalled and installed the latest version from https://extensions.gnome.org/extension/15/alternatetab/ but it did not help. I'm on Fedora 28.
