Version: (using Devel) Compiler: gcc 4.3.2 OS: Linux Installed from: Compiled sources for all svn builds I tried in the last 7 days (circa) I get the same error: kded4 crashs on log in. The crash log looks like this: cat kded4.kcrash Anwendung: KDE-Dienst (kded4), Signal SIGSEGV 0x000000315549fbe0 in __nanosleep_nocancel () from /lib/libc.so.6 Thread 1 (Thread 0x7fab9ac37750 (LWP 8408)): [KCrash Handler] #5 0x00007fab9890f8d0 in vtable for PowerDevilDaemon () from /usr/kde/live/lib64/kde4/kded_powerdevil.so #6 0x000000315d22f1a5 in QDBusAbstractInterface::callWithArgumentList () from /usr/lib64/qt4/libQtDBus.so.4 #7 0x000000315d230e7b in QDBusAbstractInterface::call () from /usr/lib64/qt4/libQtDBus.so.4 #8 0x000000315d2310f1 in QDBusAbstractInterface::call () from /usr/lib64/qt4/libQtDBus.so.4 #9 0x00007fab98035a9a in HalPower::brightness () from /usr/kde/4.1/lib64/kde4/solid_hal_power.so #10 0x00007fab984c9d3b in Solid::Control::PowerManager::brightnessControlsAvailable () from /usr/kde/live/lib64/libsolidcontrol.so.4 #11 0x00007fab984caf45 in Solid::Control::PowerManager::setBrightness () from /usr/kde/live/lib64/libsolidcontrol.so.4 #12 0x00007fab986f709f in PowerDevilDaemon::applyProfile () from /usr/kde/live/lib64/kde4/kded_powerdevil.so #13 0x00007fab986fbe13 in PowerDevilDaemon::PowerDevilDaemon () from /usr/kde/live/lib64/kde4/kded_powerdevil.so #14 0x00007fab986fdd87 in KPluginFactory::createInstance<PowerDevilDaemon, QObject> () from /usr/kde/live/lib64/kde4/kded_powerdevil.so #15 0x00007fab9b0ea834 in KPluginFactory::create () from /usr/kde/live/lib64/libkdecore.so.5 #16 0x00007fab9bdffe4e in ??

This looks more a problem with solid than with PowerDevil itself, so moving it
Hmmm, backtrace is incomplete (stops at frame #5), also it says: #5 0x00007fab9890f8d0 in vtable for PowerDevilDaemon () from /usr/kde/live/lib64/kde4/kded_powerdevil.so Looks like it's crashing into the kded module indeed (to be confirmed with a more complete backtrace though).
hm, I updated to latest svn yesterday and kded stopped crashing.
It has been crashing for me too for more than two weeks already, though the culprit is Kephal. Sometimes I cannot use cookies in Konqueror.

Please report Kephal issues in a different bug report. I am marking this as fixed, please reopen if the problem should reoccur
