Bug Description

Binary package hint: plasma-widget-networkmanagement

I tried to connect to a 802.1x secured ethernet and plasma-widget-networkmanagement segfaults each time I select the connection.

Steps:
created a new wired profile
default for everything except 802.1x Security. For 802.1x I tried several combinations (with or without user/pass, peap, ttls etc.).

Left click on systray icon, select connection and plasma-widget-networkmanagement segfaults.

Program received signal SIGSEGV, Segmentation fault.

Is this still a problem if you upgrade plasma-widget-networkmanagement to the latest version? The snapshot you are using is several weeks old.

Could you install plasma-widget-networkmanagement-dbgsym from the repository described at: https://wiki.kubuntu.org/DebuggingProgramCrash

And then in the gdb shell run "backtrace full" to get a better backtrace? Thanks in advance.
