Description Clément Guérin 2013-10-23 18:51:33 UTC 
Steps to reproduce :
1) Change org.gnome.shell.app-switcher.current-workspace-only to true
2) Leave the terminal open, and switch to an empty workspace
3) Alt+tab or Super+tab makes the shell crash instantly

sorry it was half the solution, but i still have all windows in windows switcher with curent-workspace-only, and you ?
Comment 4 Clément Guérin 2013-10-25 15:47:30 UTC 
The patch fixes the problem, awesome! Can't wait for a new point release integrating the fix.

I think you have to change :
org.gnome.shell.window-switcher.current-workspace-only

instead of :
org.gnome.shell.app-switcher.current-workspace-only

Review of attachment 258045 [details] [review]:

Fixes the problem, entirely functionnal.

Would be nice to add an empty line between the two returns like this

>     return false;
> +
> return true;

Looks like this patch hasn't been merged into gnome-3.10 branch. :(
Comment 9 Clément Guérin 2013-11-15 22:00:47 UTC 
It didn't made it to gnome-shell 3.10.2... Please fix it!
