Version:            (using KDE 4.3.0)
OS:                Linux
Installed from:    Ubuntu Packages

I upgraded Kubuntu 9.04 to run KDE 4.3.0 (using their backports repo, per instructions on the website). However, after upgrade, I cannot login to KDE because of a plasma crash at login. The backtrace indicates the crash to be in the network manager applet (specifically, the wireless interface manager), as below.

I upgraded yesterday evening (13th August 2009, 1700 PDT). Today morning I saw bug 202567 comment 1 (when filing the bug report) and did an "apt-get dist-upgrade" for good measure.



Backtrace:

Application: Plasma Workspace (plasma), signal SIGSEGV
