KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-13-generic i686

when i want to add "weather forecast" widget either on the desktop, or on the kicker or even on the the system tray of the kickr i crash plasma completely.

In normal kuubntu it works but in project neon it happens every time...and then i have to delete the /home/myname/.project-neon-kde subfolder to get it started running again :(((

help please!

symon

project neon
kde 4.7.3
