-- Information about the crash:
After bringing up the new "Add Widgets" bar and choosing to download new widgets from the internet, the respective window came up. I did not download anything. Just changed the view to "highest rated" and shortly after attempted to close the window by clicking the "X" window button. Then, the "Add Widgets" bar close along with the download window and immediately the Plasma workspace crashed.

 -- Backtrace:
Application: Plasma Workspace (kdeinit4), signal: Segmentation fault
