Rearranging desktop items crashes Plasma shell

[kwitaszczyk]

When moving a desktop item to another place, desktop freezes and apparently plasmashell crashes.

In order to prevent a crash by mistake, it is good to lock the desktop, and arrange desktop items by sorting them using a drop-down desktop menu.

The crash includes the backtrace:
