Bug#782075: gnome-tweak-tool: Crashes Gnome when reducing Number of Workspaces

[Jens Reyer]

control: found -1 mutter/3.21.91-2

Hi Andreas Henriksson,

I think I found how to reproduce this:

In a freshly installed Stretch system (my main machine) this happens
only if you've set in the Gnome Tweak Tool:

 Desktop - Icons on Desktop - On

After this as previously described:
 Workspaces - Workspace Creation - Static
 Workspaces - Number of Workspaces - Reduce by one
  --> the Desktop wallpaper gets black for a short time, then
      everything is back to normal.
 Workspaces - Number of Workspaces - Reduce by one
  --> Gnome session crashes


Further observations from my fresh installation tests on my main machine:

New Jessie installation, no changes --> crash reproducible
Update to Stretch, still no changes --> no crash
