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
