Summary: Plasma-desktop crashes when selecting the "Grid
Desktop" containment
Product: plasma
Version: unspecified
Platform: Unlisted Binaries
OS/Version: Linux
Status: NEW
Severity: crash
Priority: NOR
Component: general
AssignedTo: plasma-bugs@kde.org
ReportedBy: polentino911@gmail.com
Version: unspecified (using Devel)
OS: Linux
Today I've created a new "Grid Desktop" activity on my laptop, and
plasma-desktop suddenly crashed.
When plasma-desktop restarted there was a new "Desktop" activity.
So I've tried to change its type by right-clicking on the desktop -> Desktop
Settings -> Layout: Grid Desktop but, when I clicked "Apply", plasma-desktop
crashed again.
Same behavior with the "Grouping Desktop" containmnent. The backtrace I
collected is the following:
Application: Plasma Desktop Shell (kdeinit4), signal: Segmentation fault

Reproducible: Always
Steps to Reproduce:
Rigth click on the desktop -> Desktop Settings, then select Layout: "Grid
Desktop" or "Grouping Desktop", from whatever activity, then apply.
Actual Results:
When applying the changes, plasma-desktop will crash immediately in both cases.
Expected Results:
plasma-desktop should change the containment type without any crash.
