Ubuntu ships an old snapshot of the network management widget, or maybe knetworkmanager. Can you update to the latest SVN version, and see if it still crashes for you? I'm regularly using the kill switch myself, and haven't seen it crashing even once. Git commit d5b519eeaeccf056ca7d91d1db20cb96950b8522 by Lamarque V. Souza. Committed on 26/04/2011 at 06:41. Pushed by lvsouza into branch 'master'. Try to avoid dangling pointer when setting signal strength for an access point that has just been destroyed.

Application: plasma-desktop (0.3) KDE Platform Version: 4.4.2 (KDE 4.4.2) Qt Version: 4.6.2 Operating System: Linux 2.6.32-26-generic i686 Distribution: Ubuntu 10.04.1 LTS -- Information about the crash: The title says it all. When I use the hardware switch to switch off the wlan (whilst being connected to a network) the desktop crashes. However, after a few seconds the desktop is restarted and all my windows are still there. -- Backtrace: Application: Plasma-Arbeitsfläche (kdeinit4), signal: Segmentation fault [Current thread is 1 (Thread 0xb78b6aa0 (LWP 2898))] Thread 2 (Thread 0xa8fb9b70 (LWP 2900)): #0 0x00dc2e16 in clock_gettime () from /lib/tls/i686/cmov/librt.so.1 #1 0x006ee6fb in qt_gettime () at kernel/qcore_unix.cpp:111 #2 0x006f3825 in QTimerInfoList::updateCurrentTime (this=0xa8c7c34) at kernel/qeventdispatcher_unix.cpp:340 #3 0x006f386a in QTimerInfoList::timerWait (this=0xa8c7c34, tm=...) at kernel/qeventdispatcher_unix.cpp:443 #4 0x006f1818 in timerSourcePrepareHelper (src=<value optimized out>, timeout=0xa8fb90cc) at kernel/qeventdispatcher_glib.cpp:136 #5 0x006f18a5 in timerSourcePrepare (source=0x0, timeout=0xdc6ff4) at kernel/qeventdispatcher_glib.cpp:169 #6 0x04db9aca in g_main_context_prepare () from /lib/libglib-2.0.so.0 #7 0x04db9ee9 in ??
