knetworkmanager crashed with SIGSEGV in WirelessSecuritySettingWidget::writeConfig()

SRU Information:
Impact: Impacts a fair amount of people, the upstream bug has quite a few duplicate reports
Addressed by: http://websvn.kde.org/?view=revision&revision=1056905 which is limited to this source package
Testcase:
1) Start a connection attempt (or let connect automatically connection
activate)
2) Connection fails, for whatever reason, and the connection secrets dialog is
shown
3) Edit the connection in the KCM, not in the shown connection secrets dialog
4) Ok the connection secrets dialog
5) Crash.

Binary package hint: plasma-widget-networkmanagement

I tried connecting to a WEP-encrypted network. The first attempt didn't work - after a minute, it still wasn't connected. I tired again. After I entered the password and pressed OK, it crashed.
