Description Darin Miller 2013-09-08 03:16:46 UTC 
Application: plasma-desktop (4.11.00)
KDE Platform Version: 4.11.1
Qt Version: 4.8.4
Operating System: Linux 3.11.0-4-generic x86_64
Distribution: Ubuntu Saucy Salamander (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
When attempting to add the gmail plasmoid by Mark McCans (downloaded using the Get New Widgets option), plasma desktop crashes.  It crashes when trying to add it to the desktop and to the panel.

This plasmoid works fine with 4.11.1 on 13.04.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

New crash information added by DrKonqi

plasma-desktop (4.11.00) on KDE Platform 4.11.1 using Qt 4.8.4

While attempting to install any downloaded widget to the desktop, the desktop will black out and kwin will reload. I am able to place widgets that come with kubuntu 13.10, but not any downloaded

I don't understand how this could be a duplicate of "kwin crashing on login". I can log in just fine. I can add widgets from the default installation of 4.11 plasma. I cannot add widgets from "Download New Widgets", just as the OP can't.

Please explain? Am I missing something?

The summary provided by the reporter doesn't matter much when judging whether it is a duplicate. The backtrace does.
