Created attachment 56844 [details] Information from kcrash Version: unspecified (using KDE 4.4.5) OS: Linux I have a Cisco VPN account, so I would like to use vpnc. I have configured this VPN account correctly and, when connected via wired ethernet, I can use the VPN without any problems. However, when attempt to enable the VPN when connected use wifi then knetwork-manager crashes. Reproducible: Always Steps to Reproduce: Start KDE. Knetwork-manager is configured to auto-connect to the wireless, if found. Click on knetwork-manager icon in sys-tray. Observe that a window showing various options appears. Click on section the VPN icon for my Cisco VPN account. Actual Results: Knetwork-manager crashes I've included the stack-trace as an attachment. Expected Results: I would like the VPN connection to be established. Connecting to the VPN works fine when connected via wired ethernet. From a casual look, it seems that knetwork-manager is triggering some bug in Qt. Perhaps the GUI related activity is different when enabling VPN, between wired-ethernet and wireless. One obvious difference is the sys-tray icon changes when enabling VPN-over-wiress but with VPN-over-wired the icon remains the same. Could there be a race-condition here? The problem may be a regression of an earlier problem. Something similar happened some time ago. That appeared to have been fixed (order-of-magnitude: 6 months ago) and connecting via VPN over wireless worked fine up to yesterday. Now the problem, or a similar one, is back again. Another curious thing is that I updated neither the network-manager-kde package nor any qt library packages from Debian sid/unstable over the past few days. So it's unclear why this problem has started.
