That's weird, I've been using Arch Linux with GNOME Shell (now 42.4), and I've never encountered this. Looking at the code, this._windowSignalIds should always be a Map or null, but the error is saying the get is undefined instead of _windowSignalIds itself, so I'm confused...

@zhanghai Interesting, this isn't a problem on Arch. I'll do some more investigating this weekend and see if I can get you more information.
