Bug#1132797: gnome-shell[…]: value "nan" of type 'gdouble' is invalid or out of range for property 'value' of type 'gdouble'

[Kenny Glowner]

Hello, I would be happy to help you.

Could you open a terminal then run: journalctl /usr/bin/gnome-shell -f

Then force the trigger, it is likely caused by an extension.

We need to figure out what extension is causing NaN ( not a number).

gdoable is code framework used b GObject that powers gnome.

property 'value' probably tied to a slider like volume or brightness, 
possibly a scrollbar.

I am thinking dash-to-panel or dash-to-dock if you have that extension 
enabled.

Let me know if you figure out which extension is triggering the issue.
